A new active region referred as AR 0982 by NOAA produced several minor outbursts, the bigger one crossing the B level by a margin. We expect no significant activity from this AR within the next 48 hours. Geomagnetic activity is expected to be mostly quiet for the next 48 hours. The conditions might evolve and reach active levels by the end of February 1st due to a recurrent coronal hole. TODAY'S ESTIMATED ISN : 010, BASED ON 06 STATIONS.
