Bülletään

Solar activity was low with only four low level C-class flares (C1.7 being the maximum) from NOAA active regions 2434 and 2436 and 2437. NOAA AR 2437, which had produced a few M-class flares on October 17, has rounded the East limb only producing flares at the C-level during the past period. Catania sunspot region 52 is a new region near S09E12. No Earth- directed CMEs were observed. Flaring activity at the C-level is expected.

The solar wind speed decreased from about 480 km/s to 400 km/s. The magnetic field magnitude currently is about 5 nT with a mainly negative Bz component. Mostly quiet to unsettled geomagnetic conditions were observed, which are expected to continue. There is a chance for a few episodes of active to minor storming conditions due to the moderate speed stream from an equatorial coronal hole, expected to arrive on October 21.
