G1 Watch 4 - 5 Nov due to CH HSS Effects

G1 Watch 4-5 Nov
G1 Watch 4 - 5 Nov due to CH HSS Effects
published: Sunday, November 06, 2022 22:02 UTC

A G1 (Minor) geomagnetic storm watch is in effect for the 4 and 5 November, 2022 UTC-days. A coronal hole (CH) high speed stream (HSS) is expected to reach Earth later on 4 Nov. As the HSS reaches Earth, most geomagnetic responses are anticipated to be unsettled to active, however, isolated G1 storm levels are possible as the HSS intensifies and continues into 5 Nov. CHs are routine features during a solar cycle; to learn more about these features visit our information piece about CH HSSs. Continue to follow our webpage for the latest information, forecast, and updates. Also, this would be a good time to check out our experimental aurora dashboard to learn more about the aurora.
