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 1024 or 512 x 512, to facilitate downloading.
Access
to 512 x 512 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.

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.
