Region 7646 (S08W39) generated the majority of the days C-class flares, accounting for six. The largest flare of the day was an optically uncorrelated C6 with an associated Type II radio sweep at 06/0619Z. A new Region was assigned: Region 7650 (N04E41). Solar activity forecast: solar activity is expected to be low to moderate. The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Geophysical activity forecast: the geomagnetic field is expected to be unsettled due to numerous small flares.

High Latitudes Active 20/20/20 Minor Storm 10/10/10 Major-Severe Storm 01/01/01 HF propagation conditions were near-normal over all regions. Minor signal degradation may be sporadically observed on high-latitude circuits over the next several days, but particularly on 08 January. Otherwise, near-normal conditions should persist throughout the next 72 hours.

The geomagnetic field has been at quiet levels for the past 24 hours. High latitude stations reported active conditions from 1200-1500Z.

Several weak interplanetary disturbances may be observed from the minor flare activity that has occurred over the last several days. Otherwise, near-normal conditions will persist if these disturbances fail to arrive.

High solar flux levels denote higher levels of activity and a greater number of sunspot groups on the Sun. The 90-day mean solar flux graph is charted from the 90-day mean of the 10.7 cm solar radio flux.
