Solar activity was low. Region 1410 (N24E16) produced a single C-class x-ray event during the period.

Solar activity is expected to be very low to low over the next 3 days (31 January - 02 February).

The geomagnetic field was quiet, until the arrival of a glancing blow from the limb event CME that occurred in association with the X1/1f flare on 27 January. The transient passage was observed by the ACE spacecraft at 30/1554Z with a solar wind speed increase from around 350 km/s to near 450 km/s. A weak sudden impulse measuring 8nT was observed by the Boulder magnetometer at 30/1635Z. Conditions afterwards ranged from unsettled to quiet. The greater than 10 MeV proton that began at 27/1905Z and reached a maximum of 796 pfu at 28/0205Z was still in progress at the time of this event, with flux levels hovering near 20 pfu. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period.

The geomagnetic field is expected to be mostly quiet for days 1-3 (31 January - 02 February). The greater than 10 MeV proton flux levels, as observed by NOAA GOES-13 in geosynchronous orbit, are expected to decay below the 10 pfu threshold in the next day or two.
