Solar alert

Issued on 2024 May 15 0759 UTC

An X8.7 flare was registered by GOES-16 as peaked at 14 May 16:51 UTC. This is likely a double peaked event with the second peak around 17:00 UTC. Both peaks are associated with NOAA Active Region (AR) 3664 (Catania sunspot group 86). This event caused a halo Coronal Mass Ejection that is not Earth-directed. No proton event has been caused as a result of this flare. More X-class flaring activity is expected from this AR, however as it is currently turning behind the solar limb, this activity might get obscured.

A halo Coronal Mass Ejection (CME) can be seen in LASCO/SOHO images starting from 14 May 17:36 UTC. This event is associated with an X8.7 flare that peaked yesterday at 16:51 UTC and originated from NOAA active region 3664. As such this event is not expected to be Earth-directed.

An X3.5 flare was registered by GOES-16 as peaked today at 08:37 UTC and is associated with NOAA Active Region (AR) 3664 (Catania sunspot group 86). Although a proton event and a Coronal Mass Ejection (CME) might take place as a result, they are unlikely to be Earth-directed. More X-class flaring activity is expected from this AR, however as it is currently turning behind the solar limb, this activity might get obscured.

Issued on 2024 May 15 1527 UTC

An X3.0 flare was registered by GOES-16 as peaked today at 14:38 UTC. The source was an Active Region (AR) located at S07E90. Although a proton event and a Coronal Mass Ejection (CME) might take place as a result, they are unlikely to be Earth-directed.
