Data Access

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 6 definitive products are now available (effective June 15, 2017).  This version replaces the previous version and we encourage all users to switch to the latest version for their analyses. We have compiled a list of detailed version comparisons and validation. New files are added daily to this site.  EVE began normal operations on April 30, 2010.

 SolarSoft

• Installation form for SolarSoft – includes new installations and upgrades to existing installations
• The EVE SolarSoft package is standalone, and contains several useful functions for downloading/plotting/analyzing EVE data. Download this if you do not want the rest of solarsoft. If you already have EVE installed locally on SolarSoft, you do not need this.
