FORECAST
Space weather for the next 24 hours is predicted to be minor.
Radio blackouts reaching the R1 level are likely.
SOLAR ACTIVITY
Solar activity is likely to be moderate with a slight chance for an X-class flare on days one, two, and three (13 Aug, 14 Aug, 15 Aug).
GEOPHYSICAL ACTIVITY
The geomagnetic field is expected to be at quiet to active levels on days one, two, and three (13 Aug, 14 Aug, 15 Aug). Protons greater than 10 Mev have a slight chance of crossing threshold on day one (13 Aug).
