Latest 3-day plot

 

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.

The Latest Level 0C Spectra are available for downloading. These are 1-minute averages of the solar spectrum. The file latest_EVS_L0C.txt is updated every minute and contains the last 15 spectra. It takes about 7 minutes from the time photons are measured by EVE until the data are available in this file as a 1-minute averaged solar spectrum.

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.
 

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

SAM solar irradiance peak and centroid

SAM 0.1-7 nm solar irradiance peak centroid. The large white square is the peak location, and the diamond is the centroid.

The EVE SAM provides the best flare location information for soft X-rays.

  • SAM 5-minute irradiance peak and centroid data is available in daily ASCII files.
  • Latest & Historical 5-minute data
  • A historical 1-minute irradiance peak and centroid dataset is also available after the end of each UT day.
