G1 Watch issued for 15 Jun 2022

G1 Watch issued for 15 Jun, CME in Lasco COR2, SUVI 193 image, latest CME Enlil run
G1 Watch issued for 15 Jun 2022
published: Thursday, June 16, 2022 13:19 UTC

A G1-Minor geomagnetic storm watch has been issued for 15 Jun, 2022. The CME associated with the M3/1n flare (R1-Minor radio blackout) that occurred at 13/0407 UTC, is likely to skirt the Earth's magnetosphere at approximately the same time the onset of a positive polarity coronal hole (+CH90) is expected to impact Earth.  The combined effects will likely produce G1-Minor storming, with a chance for G2-Moderate storm levels if conditions occur simultaneously. Forecasters will be monitoring the situation and additional watches, warnings, or alerts will be issued if conditions warrant.  Visit https://swpc.noaa.gov for the latest updates and forecasts.
