Additional Comments

Solar wind speed has decreased to background levels. We are expecting QUIET geomagnetic conditions over the next two forecast periods.
In the past 24 hours, a series of B-class flares were emitted from the active sunspot region situated at the Sun's northwestern quadrant. A C-class flare was observed to have erupted from this evolving sunspot region, which began from 21/1035 before reaching its maximum extent at 20/1118 UT. The resulting CME is expected to glance the Earth as it travels further from the Sun, leading to a minor STORM event during the third forecast period. A large, Earth-directed B-class flare was also observed around midnight UT on 21-March. In the meantime, further activities coming from this sunspot region will be closely monitored.
Time of forecast: 21 Mar
