⚠️ AURORA ALERT ⚠️
The NOAA Space Weather Prediction Center is predicting the effects of recent CME will arrive Dec 30-31, likely triggering a G3-level storm.
If you are at a high latitude and lucky enough to have clear skies (not great odds in the N. Hemisphere), take a peak outside tonight!
Forecasted Timing:
Europe: Early morning Dec 31
North America: Early night Dec 30
Asia/Pacific: Early night Dec 31? (not favorable timing)
Reminder: These forecasts have a lot of uncertainty.
