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 remained at low levels, with occasional C-class flaring observed. The largest event of the period was a C3.7/Sf flare at 25/0104 UTC from Region 4447 (S17E11, Dso/beta). There are currently nine numbered regions on the visible disk. As Region 4446 (S14E45, Hax/alpha) rotated further into view, it was resolved as two distinct groups and split into Region 4446 and new Region 4449 (S10E50, Dao/beta). Region 4447 underwent notable growth with new flux emergence and consolidation of both poles. Region 4448 (S07E55, Dao/beta) and Region 4445 (N07E26, Cro/beta) also exhibited some growth. Two additional regions, 4450 (N10E49, Bxo/beta) and 4451 (S16E65, Cro/beta). The remaining regions on the disk showed minor changes or slight signs of decay. Additional activity included partial halo CME from beyond the Northwest limb that was observed in LASCO C2 beginning at 25/2212 UTC. Due to the location of origin, no geoeffective impact is expected. No Earth-directed CMEs were observed in coronagraph imagery.
Solar Activity Forecast
Issued: 2026 May 26 0030 UTC
Solar activity is expected to remain at low levels through 28 May, with an increasing chance for isolated M-class flares (R1-R2/Minor-Moderate) due to the activity of Region 4447 and the expected rotation into view of active far-side regions that supported by coronal activity observed beyond the east limb.

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.
