Solar activity was very low. The solar disk was spotless. No
Earth-directed CMEs were observed in available satellite imagery.
Solar activity is expected to remain very low on 20-22 May.
The greater than 2 MeV electron flux reached moderate levels. The
greater than 10 MeV proton flux was at background levels.
The greater than 2 MeV electron flux is expected to be at normal to
moderate levels on 20 May with high flux levels possible on 21-22 May in
response to recurrent CH HSS influence. The greater than 10 MeV proton
flux is expected to continue at background levels.
Solar wind parameters, as measured by the DSCOVR spacecraft, reflected
weak enhancements. Total magnetic field strength was between 4-9 nT. The
Bz component briefly reached a maximum southward deflection of -6 nT.
Solar wind speeds were mostly between 350-400 km/s. Phi angle was
Weak enhancements in the solar wind are anticipated in response to
multiple recurrent, negative polarity CH HSSs over 20-22 May.
The geomagnetic field was quiet to unsettled.
The geomagnetic field is expected to be at quiet to unsettled levels
throughout the forecast period (20-22 May) due to the anticipated
influence of multiple recurrent, negative polarity CH HSSs.
