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).

What's a CCD bakeout, anyway?

The entire Yohkoh data set is now 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, see:

the Yohkoh archive page, or
the Yohkoh ftp archive

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 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.
