Solar Activity was active the last 24 hours with several C-class flares and 1 M5 flare peaking around 13:32 UT on May 22d with origin AR NOAA 1745. It was associated with a proton event where levels were above the 10.0 pfu treshold for > 10 Mev, > 30 Mev and > 50 MeV. A CME associated with this M5 flare was detected by LASCO C3 around 15:00 UT, from the available information, the CME has an angular width of around 120 degrees and a speed around 1000 km/s. Based on this data the CME will reach Earth on May 25th around 17:00 UT. A second, slower CME (500 km/s) with angular width around 90 degrees was detected by LASCO C3 at 10:18 UT from the same source region (NOAA 1745) due to a C flare around 9:45 UT, this CME is not directed towards Earth and will partially dissipate in the first CME. Geomagnetic conditions where moderate (K=3) and are expected to remain quiet to moderate until the arrival of the CME on May 25th around 17:00 UT where K levels can reach major storm levels. (K = 6)
Today's estimated international sunspot number (ISN): 075, based on 08 stations.
