An interplanetary shock wave possibly associated with the M5-class solar flare of May 17th swept past Earth on May 20th around 02:00 UTC according to SpaceWeather. The shock’s arrival caused geomagnetic activity around the poles, and several outbreaks of high-latitude auroras. Click the following LINK to watch the latest CME forecast model run.

3-day Solar-Geophysical Forecast issued May 20 22:00 UTC by NOAA/SWPC

Solar Activity Forecast: Solar activity is expected to be at predominately low levels for the next three days (21 – 23 May). A slight chance for M-class activity exists all three days.

Geophysical Activity Forecast: The geomagnetic field is expected to be at predominately quiet levels for day one (21 May). By days two and three (22 – 23 May), quiet to unsettled levels with a slight chance for isolated active periods are expected due to coronal hole high speed stream effects coupled with the arrival of the 18 May CME.

  1. The energy is not restricted to the northern climes…it’s just that it’s visible to the naked eye in that area. I would say, be open to it and expect to be rejuvenated.
