**** SPACE WEATHER OUTLOOK ****
Summary For January 12-18
Space weather during the past week reached moderate levels. A category
R2 (moderate) radio blackout occurred due to M5 solar flare on January
17th. This flare originated from an active sunspot region designated
by NOAA Space Weather forecasters as Active Region 540. This Active
Region also produced a Category R1 (minor) radio blackout on January
18th. At the time of this summary issue (January 20th) Active Region
540 has produced two more category R1 radio blackouts as well as
another category R2 radio blackout. A brief Category G1 (minor)
geomagnetic storm was observed on January 16th due to high speed solar
winds 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 Scales.
Outlook For January 21-27
Space weather for the next week may reach minor levels. Category R1
(minor) radio blackouts are possible during the week since Active
Region 540 is likely to produce more category R1 and R2 radio
blackouts. 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 sun.
