Space Weather Observations, Alerts, and Forecast
3-day Solar-Geophysical Forecast issued May 18 22:00 UTC
Solar Activity Forecast:
Solar activity is expected to be at low levels with a slight chance for an M-class flare all three days (19 - 21 May).
Geophysical Activity Forecast:
The geomagnetic field is expected to be at quiet to unsettled levels with isolated active periods on day 1 (19 May) due to a possible shock arrival from the 17 May CME. Quiet to unsettled conditions are expected on day 2 (20 May). Mostly quiet conditions are expected on day 3 (21 May). There is a slight chance for shock enhancement of the greater than 10 MeV protons above 10 pfu on day 1.
This plot shows 3-days of 5-minute solar x-ray flux values measured on the SWPC primary and secondary GOES satellites. One low value may appear prior to eclipse periods.
