G1 (Minor) Watch for Thursday Evening/Night EST

G1 Watch for 9 January
G1 (Minor) Watch for Thursday Evening/Night EST
published: Wednesday, January 07, 2026 15:39 UTC

A G1 (Minor) Watch is in effect for late Thursday evening into early Friday morning EST (early on the 9 January UTC-day). A returning coronal hole high speed stream (CH HSS) is anticipated to provide the possibility for G1 activity. This is a recurrent CH HSS and it was responsible for a few periods of G1 last rotation (approximately 27 days ago). Additionally, a pair of coronal mass ejections (CME) could provide some weak, grazing influences should they pass close enough by Earth. There is a moderate level of certainty regarding CH HSS effects, but low confidence in any CME influences. As always, continue to visit our SWPC webpage for the latest information, forecasts, and updates.
