Summary For January 29-February 4

Space weather reached minor levels during the week. An isolated category
R1 (minor) radio blackout occurred on Feb. 2, due to a medium-sized
solar flare. Category R1 radio blackouts are normally associated with
the following system effects on the sunlit side of Earth: minor
degradation of high-frequency radio communication resulting in
occasional loss of radio contact and low-frequency navigation signals
degraded for brief intervals. A Category S1 (minor) solar radiation
storm occurred during Jan. 28 – 30 following a medium-sized flare near
the west limb of the Sun. Category S1 radiation storms typically result
in minor effects on high-frequency radio communication in the polar
regions. A brief Category G1 (minor) geomagnetic storm occurred on Jan.
29 due to a CME passage at Earth. Category G1 storms are typically
associated with minor effects on power systems and satellite
operations. Migratory animals are also affected at this and higher
levels of geomagnetic activity. In addition, aurora is commonly visible
at higher latitudes (northern Michigan and Maine).

Outlook For February 7-13

Space weather is expected to continue at minor levels. An isolated
category R1 radio blackout may occur some time during the period with
effects comparable to those mentioned above. No geomagnetic storms or
solar radiation storms are expected.
