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 reached moderate levels with two isolated M-class (R1-Minor) flares from the growing Region 4246 (N23W21, Dac/beta-gamma-delta): M1.9/1N flare peaking at 13/0526 UTC, and an M2.7 flare peaking at 13/0919 UTC. The earlier M-flare was associated with a faint CME, first observed at SUVI imagery and later detected in available coronagraph data. That CME showed an Earth-directed component, but further coronagraph imagery in necessary to enable modeling at this time. Multiple C-class flares were observed from the growing Regions 4246 and 4248 (N06E08, Dhi/beta-gamma-delta) during the period. The remaining five active Regions presented at the solar disk in the last 24 hr either showed decay or stability with alpha or beta magnetic classification.
Solar Activity Forecast
Issued: 2025 Oct 13 1230 UTC
Solar activity is likely to continue at low levels, with a chance for R1-R2 (Minor-Moderate) levels (associated with M-class flare occurrence) over the remaining 13 Oct until 15 Oct. 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.
