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 decayed down to low levels. The largest flare of the period was a C5.0/1n from Region 4524 (N12E26, Cao/beta-gamma) observed at 06/1042 UTC. This region continued to exhibit weak decay. New Region 4528 (S11E64, Hsx/alpha) produced a C1.1 flare at 06/1334 UTC. The remaining existing regions on the disk were quiet and stable. A halo CME associated with the C5.0 first became visible in LASCO C2 imagery at 06/1112 UTC and in STEREO coronagraph imagery at 06/1053 UTC. Modeling suggests a potential arrival at Earth late on 08 Sep-early on 09 Sep. Several additional CMEs were observed over the past 24-36 hours. These CMEs were described at length in the previous discussion. Modeling suggests a possible combined arrival for these eruptions on early 08 Sep.
Solar Activity Forecast
Issued: 2026 Sep 07 0030 UTC
Solar activity will likely be at low levels due to occasional C-class flare activity, with a slight chance for M-class flares (R1-R2/Minor-Moderate) through 09 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.
Solar X-ray Flux This plot shows 3-days of 5-minute solar x-ray flux values measured on the SWPC primary and secondary GOES satellites. |

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.
