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 email@example.com or firstname.lastname@example.org.
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.
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.
