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 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 ( https://lasp.colorado.edu/home/eve/ ).

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

For current flare indices based on ESP and proxies visit SDO/GOES X-Ray Flare Watch.

Historical SAM images can be found here and movies here.

The Latest Daily Quicklook Data file starts at 0:00 UT and is updated every minute with EVE photometer data. Another file with only the latest 15-minutes is also available.

Archived Level 0C Spectra are also available for downloading. The files contain a full days of 1 minute average spectra. We encourage users of historical data to use the 10-second spectra from the level 2 products instead, or our 1 minute spectra from the level 2b products.

ESP is used to estimate the soft X-ray solar irradiance centroid shown below.
