The largest solar event of the period was a M1 event observed at 19/2159Z from Region 3685 (S13E29). There are currently 6 numbered sunspot regions on the disk. # :Solar_Forecast: Solar Activity Forecast: Solar activity is likely to be moderate with a slight chance for an X-class flare on days one and two (21 May, 22 May) and expected to be low with a chance for M-class flares and a slight chance for an X-class flare on day three (23 May). # :Geophysical_Activity: Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 427 km/s at 20/0308Z. Total IMF reached 9 nT at 20/0041Z. The maximum southward component of Bz reached -6 nT at 20/0228Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 512 pfu. # :Geophysical_Forecast: Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to active levels on day one (21 May) and quiet levels on days two and three (22 May, 23 May). Protons have a slight chance of crossing threshold on days one, two, and three (21 May, 22 May, 23 May).
