ESA is closely monitoring a notable space weather event, first detected at 18:09 UTC on 18 January 2026.
Aurora were observed over Europe last night and continued high levels of space weather activity are anticipated over the coming days.

🧐Estimations for orbit decay by UNIGRAZ:
SODA (Satellite Orbit DecAy) provides a 15-h forecast for satellite orbit decays induced by ICMEs, having strong negative Bz.
The calculated orbit drop results are normalized for satellites at orbit heights of about 490 km.

🧐How was the ionospheric activity on this event?
Ionospheric scintillation activity nowcast for the Arctic region (ISPA) shows the different activity scintillation levels modelled on the storm onset.

🔊 Expected geomagnetic activity from UKMO
Geomagnetic activity is likely to increase with the likely arrival of an Earth-directed CME on 20 Jan, with G1-G2 storm expected and a G3 likely with a chance of G4 based on preliminary analysis of the event
🌐 swe.ssa.esa.int/metoffice-al...
🚨Associated with the X1.9 flare, a full halo CME was ejected with an estimated speed of 1250 km/s❗
