EVE Calibration Rocket, May 3, 2023, Streaming on NASA TV

All is Go for the launch of the SDO EVE calibration rocket (NASA #36.389) on May 3. The EVE Team has approvals from NASA, WSMR (White Sands Missile Range, where the flight will occur), and the Navy (who run the launch pad) for a launch window of 18:10-18:40 UTC (2:30 PM - 2:40 PM ET). The weather forecast for White Sands, NM, is also looking good.

NASA TV will stream the launch starting at 11:45 AM MDT (1:45 pm ET) at the link https://video.ibm.com/channel/nasa-tv-wallops.

Enjoy!

Congratulations to the EVE Team!

NASA 36.353 sounding rocket flight to calibrate SDO EVE and several other satellite instruments was a great success. Hre's the proof, exposures from both the MEGS-A and MEGS-B CCDs in the calibration EVE. The top image is from the MEGS-A CCD with MEGS-A1 spectrum on top and MEGS-A2 spectrum and MEGS-SAM X-ray image on the bottom. The bottom CCD image is the MEGS-B spectrum that goes diagonally across the CCD. The bright (yellow and red) vertical stripes are the spectral lines of the Sun that EVE studies. Just seeing these spectral lines means our Sun has a magnetic field. Without the magnetic field this part of the spectrum would be empty.

I can't wait to see the movie.

Congratulations to the EVE for a successful flight!

EVE Calibration Rocket Flies Above New Mexico

On Wednesday, June 1, 2016, the EVE calibration rocket flew high above the New Mexican desert. The instruments all returned good data and the payload was recovered for another flight in a couple of years.

Congratulations to the EVE team for re-flying the payload after last year's lunch problems. Thanks to the Wallops flight crew and the White Sands Missile Range personnel who actually do the launch and recovery.

EVE MEGS-A and SAM have been Turned Off

I am very sad to say that SDO has decided to turn off EVE MEGS-A and EVE SAM. The EVE MEGS-A/SAM instrument has had a failure in the CCD electronics. The EVE team is looking at ways to start them again, but we do not have a date for restarting the instruments.

The discovery of late-phase flares depended on the linking of MEGS-A spectra and AIA images. The SAM images were made by a pinhole camera, but had a remarkable accuracy in determining the location of flares.

MEGS-B, MEGS-P, and ESP are working as designed.

This letter from Tom Woods, the EVE PI, was sent out yesterday.

Hi EVE team,

We're sad to report that EVE MEGS-A / SAM data stream has ended on Monday May 26, 2014 due to a power anomaly for MEGS-A CCD electronics. With the SAM images being from MEGS-A CCD, both SAM solar X-ray images and MEGS-A spectra (6-37 nm) are not available now. The MEGS-A and SAM data from May 1, 2010 to May 26, 2014 will remain available from the EVE web site ( http://lasp.colorado.edu/home/eve/ ).

All the other EVE instruments are working well, ESP, MEGS-B, and MEGS-P. We¹ll be working with the EVE science team to optimize the EVE observations with those instruments.
