Summary For February 18-24

Space weather reached moderate levels during the period. Isolated
category R1 (minor) radio blackouts occurred on February 18 and 20 – 22
due to moderate-sized solar flares. A category R2 (moderate) radio
blackout occurred on February 20 due to a major solar flare from the
Sun’s western limb. This flare also caused a brief category S1 (minor)
solar radiation storm on February 20. There were no geomagnetic storms
during the period. For a list of adverse system effects related to
space weather, please refer to the NOAA Space Weather Scales.

Outlook For February 27-March 5

Space weather is expected to be at minor levels. Isolated category R1
(minor) radio blackouts are likely. There will be a slight chance for
category G1 (minor) geomagnetic storm conditions during March 4 – 5 due
to an expected increase in solar wind velocities.
