Arriving a little later than predicted, the CME associated with the eruption on July 30th reached Earth today at 12:29 UTC (Aug 2). The minor (G1) storm threshold was reached at 17:12 UTC. With the Bz component of the interplanetary magnetic field (IMF) sharply south at times, there will remain a chance for moderate (G2) storming as well. More to follow whenever necessary.
UPDATE: The moderate (G2) storm threshold was reached at 17:59 UTC (Aug 2).
Space Weather Update
August 1, 2026 @ 13:40 UTC
Welcome to August!
Solar activity during the past 24 hours was low with only minor C-Flares detected. What has my attention today is this solar filament that gradually grew more prominent over the past 24 hours and is in close proximity to AR 4498 / 4500. Should it become unstable and erupt, the chances for an Earth directed CME will increase since the region is now almost directly facing our planet. Nothing is for certain however, this is just an observation.
A reminder that a minor (G1) to moderate (G2) geomagnetic storm watch is in effect for the next 24 hours. A CME that left the Sun on July 30th is expected to glance past Earth, possibly by later today (Aug 1 UTC).
