Summary of Space Weather Observations

The Summary of Space Weather Observations, issued daily at 0030 UTC, is a summary of the previous day's solar region observations.

Note: The summary consists of observations from approximately half a dozen observatories for each active region. The sunspot counts are typically higher than those reported in non-real time by the Sunspot Index Data Center (SIDC), Brussels, Belgium, and the American Association of Variable Star Observers.
