We’re sad to report that the EVE MEGS-A / SAM data stream ended on Monday May 26, 2014 due to a power anomaly. Both SAM solar X-ray images and MEGS-A spectra (6-37 nm) are not available now. Historical MEGS-A and SAM data from May 1, 2010 to May 26, 2014 will remain available from the EVE web site.All the other EVE instruments are working well, ESP, MEGS-B, and MEGS-P. We will be working with the EVE science team to optimize the EVE observations with those instruments.
EVE Science Data Access – Routine Data Products
The Version 5 definitive products are now available (effective December 30, 2014). Version 5 replaces version 4 and we encourage all users to switch to version 5 for their analyses. We have compiled a list of detailed version comparisons and validation. Additional new files are added daily to this site. EVE began normal operations on April 30, 2010.
