Bulletin

The only C-class flare reported in last 24 hours was the C1.1 flare which peaked at 06:22 on January 16. The flare originated from the active region at the East solar limb and was associated with narrow CME (about 40 degrees) which is not Earth directed. The low C-class flares are probable in the following 24 hours. The Earth is currently inside a slow solar wind with a speed of about 400 km/s. The interplanetary magnetic field is still stable with the magnitude between 2 and 3 nT. The geomagnetic conditions are quiet and expected to remain so in the following 24 hours. The glancing blow from the CME-driven shock wave, associated with the partial halo CME first seen in the SOHO/LASCO C2 field of view at 09:36 UT on January 14, is expected to arrive at the Earth on January 18. It may cause unsettled to active geomagnetic conditions.

Today's estimated international sunspot number (ISN): 066, based on 04 stations.
