Solar alert

Issued on 2022 Sep 24 1229 UTC

A partial halo CME was detected in coronagraph data. It was associated to the eruption around noon yesterday of a filament stretching from Catania group 35 (NOAA active region 3102) towards the West. The CME is first visible in SoHO/LASCO C2 data at 13:48UTC and propagates mainly towards the West with an angular extension reaching around 180 degrees. The projected speed is measured as just over 500 km/s and estimates of the speed along the line of propagation are up to 600km/s. Given the location and direction a glancing blow from this CME cannot be excluded and if so, would preliminarily be expected in the morning of September 27. A more detailed model run is being prepared and analyzed.
