Solar alert

Issued on 2024 May 16 0958 UTC

The global geomagnetic conditions reached moderate storm levels (NOAA Kp 6) since today 06:00 UTC. This is the result of a Coronal Mass Ejection (CME) arrival today at 05:15 UTC. The geomagnetic conditions are expected to remain at storm levels for the next several hours.

Issued on 2024 May 16 1314 UTC

A Coronal Mass Ejections (CME) seen in SOHO/LASCO images as launched at 15 May 08:27 UTC is believed to be two separate CME originating from NOAA Active Regions (AR) 3670 and 3664. The first one is expected to arrive at Earth's environment on the second half on 17 May. The second is expected to deliver at most a glancing blow earlier the same day. A CME that registered in SOHO/LASCO images as emitted at 14 May 18:36 UTC is associated with the X8.7 flare of 14 May and is expected to deliver a glancing blow during the second half of 17 May. Due to the expected arrival of the CME of 15 May at approximately the same time, this glancing blow might not be apparent.
