EARTH-DIRECTED SOLAR FLARE
Posted: 21 Mar 2019, 14:16
On 20th March, a new sunspot exploded at 11:18 UT, producing a C4-class solar flare that lasted more than an hour and affected the Earth's atmosphere. This caused a shortwave radio "brownout" over southern parts of Europe and all of Africa. Anomalies in radio propagation at frequencies below 20 MHz might have been noticed by, e.g., mariners and ham radio operators.
he CME is heading for Earth. While the bulk of the cloud appears set to miss our planet, the flanks of the CME should deliver a glancing blow. Estimated time of arrival: Late on March 22nd or sometime on March 23rd. NOAA forecasters favor the March 23rd estimate. Either way, moderate (G2) geomagnetic storms are possible when the CME arrives.
