The main region producing flares is NOAA AR 11389, which has produced a few C flares in the past 24 hours. The partial halo CME detected first by LASCO C2 on January 1, 13:36 UT was a backsided event, and is not expected to be geo-effective. Geomagnetic conditions are expected to remain mostly quiet during the coming days, with possible effects from a coronal hole high speed wind stream. TODAY'S ESTIMATED ISN : 064, BASED ON 04 STATIONS.
