Summary For January 5-11

Space weather during the past week reached moderate levels. A number of
R2 (moderate) radio blackouts occurred due to M-class solar flares on
January 5th through the 7th. The largest of these flares was an M8
flare at 3:27 a.m. MST on January 7th (1027 UTC). All of these flares
originated form an active sunspot region designated by NOAA Space
Weather forecasters as Active Region 537. Category R1 (minor) radio
blackouts were observed on January 8th and 9th due to continued M-class
activity from Active Region 537. Two Category G1 (minor) geomagnetic
storms were observed last week. One occurred late on January 6th
through the 7th and the other occurred on January 9th and 10th. These
two storms were due to high speed solar wind interacting with the
Earth’s magnetic field. For a list of adverse system effects related
to space weather storms, please refer to the NOAA Space Weather

Outlook For January 14-20

Space weather for the next week may reach minor levels. Category R1
(minor) radio blackouts are possible since there is a chance of
increased solar flare activity during the week. There is a slight
chance of a category G1 (minor) geomagnetic storms on January 16th and
17th as high speed solar winds are expected from a coronal hole on the
