2026-08-27 00:36 AM WATCH: Geomagnetic Storm Category G2 Predicted Highest Storm Level Predicted by Day: Aug 27: G1 (Minor) Aug 28: G2 (Moderate) Aug 29: G2 (Moderate) THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT Comment: HSS on 27 + CMEs on 28-29. CORRECTED 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.

(Negative numbers mean amount of water needed, positive numbers mean excess water is present).   6 Air Quality Index is provided by Luftdaten System esp8266 and is updated every 5 mins..   9 Solar Index represents either an absolute scale of solar energy (W/m²) using the station’s recorded maximum or a percentage of computed theoretical solar maximum using the station’s location and time of day. These indices differ most when the sun is low on the horizon. The current scale is shown, and will toggle if it or the icon is clicked.   10 Historical average only to day 27 of just the month of August for this station since 2016.   11 Historical average rain this season to day 27 of August for this station since 2016.
