The CME’s impact sparked a G1-class<\/a> geomagnetic storm<\/a> with photographic auroras in the USA as far south as Shenandoah National Park in Virgina. Subscribers to our Space Weather Alert Service<\/a> received a “heads-up” text message 30 minutes before the CME struck, giving photographers time to dash outside and position their cameras.<\/p>\n\n\n\n

Space Weather Message Code: WARK06
Serial Number: 459
Issue Time: 2022 Jul 23 0456 UTC<\/p>\n\n\n\n

WARNING: Geomagnetic K-Index of 6 expected
Valid From: 2022 Jul 23 0455 UTC
Valid To: 2022 Jul 23 1800 UTC
Warning Condition: Onset
NOAA Scale: G2 – Moderate<\/p>\n\n\n\n

NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov\/noaa-scales-explanation<\/p>\n\n\n\n

Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents – Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft – Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio – HF (high frequency) radio propagation can fade at higher latitudes.
Aurora – Aurora may be seen as low as New York to Wisconsin to Washington state.<\/p>\n","protected":false},"excerpt":{"rendered":"
