Solar alert

Issued on 2023 Jun 21 1415 UTC

A partial halo Coronal Mass Ejection (CME) was automatically detected by CACTUS as launched yesterday 17:24 UT. It was caused by the X1 flare emitted from NOAA active region 3341, located at the west solar limb. Due to the location of its source, only a glancing blow is expected to become geo-effective in the second half of 23 June.
