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).


EIT images are back!

SOHO, now in gyroless operation, started producing EIT images again late on 1999 February 2. We expect the images to be oriented with solar north "up" again sometime early in March.
Access to full resolution representations of EIT images in all four wavelengths is available at the EIT images page .

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.


Other resources for solar imagery and related solar-terrestrial observations:

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 2048 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.
