Bülletään

Solar activity was restricted to a handful of C-class flares, with a C3.9 flare as strongest one peaking at 17:27 UT on October 19. The C3.9 flare originated from NOAA 2436. Regions NOAA 2434 and 2437 also contributed to some flaring. NOAA 2436 has shown some minor growth in the number of spots. Flaring activity at the C-level is expected to continue. No Earth-directed CMEs were observed in the SOHO/LASCO images.

The solar wind speed was steady between 350 and 400 km/s, while the magnetic field magnitude reached maximally 6 nT. The phi angle was variable from 22:30 UT between a positive and negative orientation. Mostly quiet (K<3) to unsettled (K=3) geomagnetic conditions were observed, which are expected to continue. There is a chance for a few episodes of active (K=4) conditions due to the moderate speed stream from an equatorial coronal hole, expected to arrive on October 21.
