An Aurora Storm

 Was just about to write a post about autumn colours, when I looked outside, and noticed a faint glow in the sky. An initial photo seemed to reveal a faint pink glow, but when I went out again about 15 minutes later, the glow in the sky was visible to the naked eye.

Turn a phone camera to it in night sight mode, and by golly, you get spectacular results!

The Glorious Aurora

 Friday night, as I'm sure all my readers know, saw what I suspect was the greatest auroral display seen in this country in my lifetime, with only the event of March 1989 coming close. 

Early in the evening, I'd noticed reports on social media of the aurora being visible in Europe, but hadn't seen any reports from the UK. However, when I left my home at about 1130pm in order to nip across the road to the pub, I noticed what looked like blue clouds directly overhead.

On a hunch, I used the night mode on my phone to take a shot; with the greater light gathering mode, vivid blue arcs were revealed. 

Walking further round the road, a bright band was seen extending across the sky, a photo of this revealed a lurid violet sunset effect stretching across the sky. This was definitely the aurora. Social feeds from the UK revealed picture after picture, most more spectacular than mine. 

It didn't look too good to the naked eye amidst the streetlights, but the photos revealed a lot more. I did a bit of outreach in the pub garden, and soon more photos were being taken. 

I hope you got the chance to see it!

Constellations and the March of Time

 After an intense period of trying to organise a children's party - lots of walking, lots of cycling in the rain, getting locked in a venue - I've not had much time to write for you this last week, and the freezing weather has prevented any expeditions on the bike. 

Ugh, how fat winter makes me feel. 

-7 nights however have proved to be a blessing, with infinite skies diamond strewn with stars. Mars shines red among them, and I got some ok photos with my Pixel 6A of Gemini, Auriga, Taurus and Orion, the great winter constellations.

The universe is crazy to think about, how these balls of firey fusion energy of varying luminosities and colours randomly scattered in the cosmos, form these patterns that are immediately familiar - I've known the form of Orion since I was a small child. 

It will still look the same when I'm a very old man, but at a universal scale this is nothing. Eons from now, these patterns will have been destroyed by the march of space time.

Almost too much to think about.

The Mighty Hunter

 My new phone, a Google Pixel 6A (and no they aren't paying for me to write this article!) has a night shooting mode on it, the first phone I've had that can do this.

To my delight, I've found that this has enabled me to dabble in some very basic astrophotography now that I can record brighter stars in the results. 

There is one constellation that is an obvious target because of this, because it has a number of bright stars in a small area, and that is of course the mighty hunter, Orion. 

The most magnificent constellation visible to Northern Hemisphere viewers, it really is one of the few constellations that can be said to resemble what it is meant to represent. The main group of seven stars you can imagine forming his belted tunic, with a smaller group to the right resembling perhaps an arm raising a shield, while a group to the left could be an arm raising a sword or club. 

The stars you can see in this photo represent some of the largest and most luminous stars that can be seen in the night sky, most remarkable of them being the famous Betelgeuse, seen here at the top left. It is a red hypergiant star that is expected to go supernova in some point in the near future in cosmological terms - in other words, within a few thousand years. When it does go bang, it will be bright enough to see in daylight, and to read by at night. 

You can just about make out the orange tint in this photo. 

Rigel, at the opposite corner is brighter and a rather different star - it is a blue supergiant that also may go supernova, but much further into history. Between them is the belt, Alnilam, Alnitak and Mintaka, all very luminous too. Amazingly, beneath them you can just make out a faint fuzz that marks Orion's sword, the nebula Messier 43 where new stars are being formed. 

If you get a clear night, do take a look, although you might have to stay up late at the moment - I took this photo at about 4am!

A Celestial Event

 We have had a period of unbelievably gloomy weather the last few days - continual fog and mist, the air full of moisture that made the rim brakes on my bicycle scarily useless at times, and a sun that may not exist anymore for all I've seen of it. 

Earlier in the week however, I accidentally saw a wonderful sight in the night sky as I was cycling home from work, and stopped to take photographs. The moon, Jupiter, Saturn and Venus were all in a line across the night sky just after sunset, with Venus just hovering above the lights of the industrial estate of food factories and chicken hatcheries. 

Sadly Saturn was a mite too faint for my camera to pick up. The next mobile phone I get better have a night photography mode on it!

This weekend, I've managed to get some decent walking done, although there hasn't been an awful lot to see apart from bare trees in a clinging damp fog. However, my attempts to find the first flowering plant of the new season in the cemetery have succeeded, and it was not what I expected. 

Was it a snowdrop or a winter aconite? 

No. It was a red dead nettle, which come March will form a vital source of nourishment for early pollinators. 

Of course, at the moment there is nothing flowering.

Celestial Bodies

Lovely close approach of Venus and the crescent Moon tonight, dominating the skies as I rode home and then went shopping later on.

The only thing other than the moon you will see at night that is brighter than Venus, is a supernova. Remember that. You never know when it may happen.

The building works at the old Robin Hood Hotel have required the arrival of a crane, that oerlooks my garden like one of the sinister Deceptacons from the Transformers movies.

Cycling to Venus and the Moon

The close conjunction of Venus and the thin crescent moon last night captured a lot of attention from casual observers, and many pictures found their way into my twitter feed of this beautiful celestial conjunction in various settings. Over Salisbury cathedral, in a glowing twilight, over peaceful waters and quiet towns and farmer's fields.

My picture is a rather more urban capture from my ride home last night!

Also in the night sky, the dimming of the star Betelgeuse - don't even think of pronouncing it Beetle-Juice no matter how many times Brian Cox says it that way - in Orion has also attracted a lot of attention. Normally one of the ten brightest stars in the sky, this vivid orange-red star is typically easily identifiable as the left shoulder of Orion, the most distinctive constellation in the sky.

But in late 2019, it began to fade, and now in late January 2020 it has become fainter by a factor of 2.5. Now Betelgeuse's eventual fate as a supergiant star has long been thought to be exploding as a type 2 supernova, and there has been much speculation that this sudden fading is a precursor to its collapse and explosion.

I wish so much that this would happen in my lifetime - when it does so it will be as bright as the full moon for a few weeks and as I read today it would be the most significant event in the history of astronomy on this planet. But chances are it may still have the odd hundred thousand years to go.

Spectacular though it would be for us, for any civilisation within 50 light years of the star the resulting radiation from the explosion would destroy it utterly.

At 700 light years, we believe we are safe...

The Rising of the Wolf Moon

The moon seems to be many things these days, blue, blood, and now wolf, and I have no idea what any of them are. What's a wolf moon? Is it hungry like the Duran Duran song? Does it cry like A-Ha sang it did? No bloody idea.

I didn't even know it was a wolf moon when I was incredibly lucky to see it rise exactly as the sun set this evening, and get some rather ropey photographs. Later on it became the "Wolf Moon", and my stepfather had a crowd of folk looking at it through his theodolite on the street - pop up astronomy!

There has also been a penumbral eclipse, although to be honest I doubt anyone could really tell the difference!

Eclipse Fail

I did stay up for the total lunar eclipse last night, hoping that in the end the clouds would part an allow me a glimpse of the moon turning that potent crimson colour - everyone else says "blood red" and I  refuse to succumb to that cliche! - as it passes through the shadow of mother earth.

Of course the clouds never did part, so all I got for my troubles was very cold, very tired, and thus stressed for the visit of my landlord and a valuer to my flat. On a bright clear day good for photography, I  then had to stay home waiting for a plumber to show up to fix my kitchen tap.

The only wildlife I saw all day were these two.

Venus before Dawn

I've noticed Venus high in the sky in the pre-dawn twilight while riding my bike to work in the last couple of  weeks, but I haven't seen it in a truly dark sky setting until this morning at 5am, where it was blazing low down along the road as I pottered about, unable to sleep.

It really is a stunning object at its maximum magnitude.

Earlier on, I'd had a good evening's observing with my binoculars, again spotting Comet Wirtanen which I think is now on the fringes of naked eye visibility, despite what I said a couple of days ago. Too bad moonlight will obliterate it from here on in.

I also observed all manner of star clusters, some like the Mirfak cluster in Perseus which are larger than my binocular field of view, and others that are far less prominent like the three Messier clusters in Auriga - 36,37 and 38.

Comet Wirtanen itself was just about in the same binocular field of view as the most famous star clusters, the Seven Sisters, or Pleiades, in Taurus.

I enjoyed taking in the sights, on what was a much milder evening than a couple of nights ago.

Gemind Meteors and Comet Wirtanen

Well, I was awake as the sun rose, awake as it set, there as the moon rose, and there as it set.

Only one of those times is significant, the time of moonset. For this would take its ivory glow out of the sky and let the night darken for the two major astronomical events of the night.

The Geminid meteors, and Comet Wirtanen.

I'll get the Geminid meteors out of the way first. These days it is regarded as the best UK meteor  shower to watch, not so much because of the number of meteors you see, but because unlike the Perseids in August, the radiant rises at a much earlier hour and you don't have to stay up till past 1am to get good shooting star views.

Although, you know, freezing cold.

They were actually quite disappointing! Yes I saw a few meteors, but nothing particularly bright, let alone spectacular. And fewer than I was expecting given that late on when I was observing the radiant wasn't far enough off the zenith. Boo hoo.

Now to Comet Wirtanen.

This comet has a period of 5 and a half years, is barely a mile across, and like most short period comets normally requires a telescope the size of a cannon to see it. But due to freak things like Newton's laws, the comet is in its best position for observation from the Earth. Of all time, past and future.

Last night, I managed to see it. OK, it was a misty blob of very low surface brightness about half the size of the full moon. Magnitude 3 maybe, but so diffuse the chance of seeing it naked eye as the newspapers have suggested are virtually zero unless you are in a dark  sky park at least 50 miles from the nearest glow-worm.

But I saw it!

I don't see many comets, so to see this misty blob is a rare treat. It made up for the underwhelming meteors. It also convinced me eyes are still just about OK too.

Moon and Venus on a Bicycle

It was a freezing morning today, which meant I got to wear the neck warmer I bought yesterday and thus set off for work feeling like a Poundland lady ice skating coach from Omsk. It did help though.

I drew the line at the balaclava until it gets colder. It is too gimp like.

My hand thermometer told me about zero degrees and that indeed was what it was. Having read lots of  reports on twitter I wondered why I wasn't seeing Venus. The answer was that I was looking in the wrong direction - Venus in the morning is in the Eastern sky, idiot!

Dawn wasn't far off but it was still a very bright object, with the added bonus of there being a beautiful thin sliver of moon nearby.

Obviously my phone doesn't take great pictures of astronomical objects, but I  hope I've picked up the flavour of my cold, crisp morning.

Lights, Moon and Lights

We've had some very wild days the last few days, my to and fro bicycle commutes have been rather interesting. I have been incredibly busy at work  preparing our Christmas events.

We now have Christmas lights on in town and I have been photographing them  in relation to the moon and things.

Evening Skyscapes

After my tumultuous floor mopping exploits yesterday, I was rather knackered today and knowing I was going to have a workout in the evening - 65 minutes on the exercise bike - I took it easy and ended up repeatedly falling asleep while watching Hugh Jackman in "Logan".

Eventually I went out to  sort some library books out, and enjoyed the crescent moon, joined nearby by planet Saturn as the evening darkened.

I may do some astronomy later, or carry on watching Luther boxsets.

More Skies

This week sunset has put on an incredible display, high altitude crystals, Rayleigh Scattering, smoke from the sugar factory and power station.

The sky goes gold as the lower edge of the sun skims the horizon, then the dark violet band of the girdle of venus appears and the lower clouds go purple, and the higher ones go gilded orange; vapour trails from escaping jets leave temporary scars across the vault.

It's beautiful.

The Alignment of Winter Solstice

I did manage to get out for two walks today, and also to conduct various bits of Christmas business, so I've been feeling a little bit better today. The warmer weather expected for today had still not arrived, and as I write, a mist is forming to ensure a tricky ride in to work in the morning.

Sunset today found the sky clear, and a strange effect took place along certain streets of Newark, as Winter Solstice approaches.

In neolithic times, the wise men of the day bought buildings and formations of stone that would align with the rising and setting of the sun, the moon, or perhaps the stars, at certain times of the year. Stonehenge is the rising of the sun at midsummer. At Newgrange the sun shines straight down the entrance to the burial chamber at midwinter. Some of the Nazca lines in Peru are reckoned to line up with the stars of Orion's belt.

Here in Newark, there are two streets aligned with the winter sun; Cartergate, where the orange glow at sunset lights up the three nail bars and four vape shops - and a Cash Converters! - and Millgate where orange rays light up the more socially acceptable housing and only the one beauty parlour.

Perhaps modern man, like his ancient coutnerpart, feels the need to line up his constructions with the forces of the universe. Perhaps it is ingrained in us.

Sun and Moon

Had a really tiring day at work yesterday, running around like a maniac sorting out Black Friday stuff for our staff. It really caught up with me; I just could not wake up this morning and ended up falling asleep in the bath.

Luckily with my head above water.

My time outside consisted of shopping, and getting my hair cut; really was rather untidy looking. And the Cadfael bald patch is rather too evident unless I keep it short. Oh well, I'm 6 foot 1 so if I stand up all the time people won't notice.

The moon in the sky is better than the moon on my head.
