The Sun produced four C-class flares during the past period. The strongest flare was a C7.7 flare (peaking at 17:56 UT on October 21), originating from NOAA 2436. NOAA 2434 produced a long duration C4.4 flare (peaking at 3:40 UT on October 22), accompanied with a dimming and a CME. The CME was first observed in LASCO/C2 at 3:12 UT and is propagating southwest of the Sun-Earth line with a projected speed of about 800 km/s. Potentially an Earth-directed component will arrive on October 24. Flaring at the C-level is expected, but also an M-class flare is not excluded.
The solar wind speed gradually decreased from 450-480 km/s to current values near 400 km/s. The magnitude of the interplanetary magnetic field started at 10 nT, but quickly lowered to 5 nT. Geomagnetic conditions were quiet to unsettled and are expected to continue. The CME of this UT morning may cause a disturbance on October 24 around noon.
Today's estimated international sunspot number (ISN): 096, based on 09 stations.
