Solar alert

Issued on 2023 Nov 26 0928 UTC

Geomagnetic conditions reach moderate storm levels (NOAA Kp and local K BEL 6) at 25th November 21:00UT, due to the influence of the high speed stream emanating from the mid latitudinal positive polarity coronal hole that crossed central meridian on 23rd November that were in turn preceded by the arrival of the ICME from 22nd November 06:48UT. The ICME arrival created minor storm geomagnetic conditions globally (Kp 5) and active conditions locally (K_Bel 4). The influence of the high speed stream is currently waning. However, it is not clear whether the second ICME (from the CME occurring at 22nd November 21:12UT) that was early 26th November has arrived as well.
