AAVSO Newsletters

195 Å Sun

We take the stability of the sun for granted. As this UV image shows, the sun is indeed variable. The AAVSO collects data on sunspots and Sudden Ionospheric Disturbances (SIDs) caused by solar flares. This data is reported monthly to NOAA. More information on the solar division can be found here.
