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. Several low level C-class flares were observed from an unnumbered Region rotating onto the SE limb near S12. Slight growth was observed in Regions 3205 (S23W56, Cao/beta) and 3206 (S22E54, Cro/beta). The rest of the spotted regions were either stable or in decay. Other activity included a filament eruption centered near S58W50 beginning at 29/1157 UTC in H-alpha imagery. A CME was observed in STEREO A COR2 imagery beginning at 29/2338 UTC that was likely associated with the event. The CME is not expected to be geoeffective. No Earth-directed CMEs were observed.
Solar Activity Forecast
Issued: 2023 Jan 30 1230 UTC
Solar activity is expected to be low, with a slight chance for M-class flares (R1-R2 Minor-Moderate) on 30-31 Jan and 01 Feb, mostly due to activity from active regions on the SE limb. 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.
