Solar alert

Issued on 2023 Dec 18 1114 UTC

Geomagnetic conditions have reached moderate storm levels globally (Kp 6) and active condition levels locally (K_Bel 4) starting at 06 UT on Dec 18, due to the continuous impact of the several ICMEs that departed the Sun from Dec 14 and early Dec 15. Further active to moderate geomagnetic storm conditions may be expected in the next 24 hours possibly due to the arrival of high speed streams from the coronal hole which crossed the central meridian on Dec 17.
