G1 Watch issued for 15 Jun 2022

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.
