Solar alert

Issued on 2023 Aug 01 1339 UTC

A partial halo Coronal Mass Ejection (CME) has been seen in SOHO/LASCO-C2 images, launched today around 00:12 UTC. This partial halo CME consisted of three different CMEs. The first CME was observed with its main component in the NE direction and is believed to be a back-sided event. The second CME observed at SE of the solar disk is a partial halo with an angular width of about 120 degrees and a projected speed of about 300 km/s (as detected and measured by the Cactus tool). This CME is associated with the filament eruption near the central meridian. The third CME is related the NOAA AR 3392 activity which is more towards the east and away from the Earth. Due to the low speed and the non-Earth directed CME components, no impact on the geomagnetic activity is expected.
