Current solar images

Click on any of the following thumbnail images for the most recent, full-resolution solar image of each type in the SDAC archive (the time and date of the image are in square brackets after the description).

Note: The SOHO EIT images are now 512 x 512 GIFs, whether their original size was 1024 x 1204 or 512 x 512, to facilitate downloading.

The entire Yohkoh data set up to one year before present is available for scientific and educational use, thanks to the generosity of the Yohkoh science team. If you know the dates and times for which you would like data, and from what Yohkoh instruments, send an e-mail request to yohkoh_sdac@solar.stanford.edu or gurman@sdac.gsfc.nasa.gov.

Data requested in this manner can be found here via anonymous ftp.

If you are unfamiliar with the Yohkoh instruments or the analysis software, consult the online introduction to the analysis of Yohkoh data.

Grey-scale representations of the He I 10830 Å spectroheliograms, as well as FITS files of the daily magnetogram and He I data, are available from NSO via the Web or via anonymous ftp at argo.tuc.noao.edu, under kpvt/daily.

Full 2038 x 2048 resolution FITS files of the NSO Sac Peak Ca II spectroheliograms, as well as H alpha FITS and GIF images, are available via anonymous ftp.

Sorry, we can't guarantee that the most recent image of each type was obtained in the last 24 hours: curious agglomerations of water vapor and dust called clouds sometimes appear over observatories on Earth, and even people who operate spacecraft take a day off from time to time.
