in Greenbelt, Maryland USA.
Current Solar Images
for the latest ground- and space-based solar images in the SDAC archives.

SolarMonitor hosted at the SDAC
now features RSS feeds with active region closeups.|
Peter Gallagher's SolarMonitor, the Website formerly known
as the Active Region Monitor, is hosted at the SDAC, as well as other sites. SolarMonitor offers up-to-date
information on solar activity, including images, flare locations, flare
predictions, and links to the LMSAL
events" page, which gives a graphic view of solar and heliospheric
activity through soft X-ray, energetic proton, and solar wind data.
Sam Freeland of LMSAL has generated an archive of "latest events"
pages from 2002 to the present, at

SOHO is in normal mode, and all instruments are observing. The coarse
sun pointing attitude anomaly detector has been reenabled.
Why 1 Tbyte/day doesn't scare us
Some people appear to think that the expected
Solar Dynamics Observatory downlink
rate of 1 Terabyte (Tbyte) = 1000 Gbyte a day is lot of data. Since SDO
won't be launched until late 2007 at the earliest, we
don't. See why.
Twin comets race to fiery death!
....or words to that effect: see two Kreutz sungrazers barrel toward the LASCO
occulting disks, and then watch the CME's and a spectacular eruptive
prominence. Check out the:
