The sun is constantly monitored for sun spots and coronal mass ejections. EIT (Extreme ultraviolet Imaging Telescope) images the solar atmosphere at several wavelengths, and therefore, shows solar material at different temperatures. In the images taken at 304 Angstrom the bright material is at 60,000 to 80,000 degrees Kelvin. In those taken at 171 Angstrom, at 1 million degrees. 195 Angstrom images correspond to about 1.5 million Kelvin, 284 Angstrom to 2 million degrees. The hotter the temperature, the higher you look in the solar atmosphere.
Solar activity was at low levels. Region 3105 (S16W36, Cai/beta-gamma) continued to decay while becoming marginally more magnetically complex. This region also produced a C5/sf flare at 27/1957 UTC, which was the largest of the period. Mixed polarities were also observed around Region 3107 (S25W19, Eai/beta-gamma), but overall its presentation was unchanged. Region 3108 (S13, L=210) decayed to plage. Region 3110 (N15E14, Cai/beta) lost penumbra on its trailing spot, but several intermediate spots remained. Region 3111 (N27E62, Hax/alpha), numbered this period, was stable. A filament eruption was observed in the proximity of the trailer spots of Region 3110 in GONG H-Alpha imagery near 28/0230 UTC. There was also an eruption (~27/2230 UTC) and subsequent dimming (~28/0400 UTC) visible in SUVI 195 imagery. A series of CMEs were observed off the east limb beginning near 28/0125 UTC. Analysis/WSA Enlil modelling is underway at the time of this writing to determine if there is any geoffective potential.
Solar Activity Forecast
Issued: 2022 Sep 28 1230 UTC
Solar activity is expected to be low with a chance for M-class flare (R1-R2, Minor-Moderate) on 28 Sep, and a slight chance for M-class flares on 29-30 Sep. Energetic

The Solar Cycle is observed by counting the frequency and placement of sunspots visible on the Sun. Solar minimum occurred in December, 2008. Solar maximum is expected to occur in May, 2013.

Instruments on board the NOAA Polar-orbiting Operational Environmental Satellite (POES) continually monitor the power flux carried by the protons and electrons that produce aurora in the atmosphere. SWPC has developed a technique that uses the power flux observations obtained during a single pass of the satellite over a polar region (which takes about 25 minutes) to estimate the total power deposited in an entire polar region by these auroral particles. The power input estimate is converted to an auroral activity index that ranges from 1 to 10.
