Bulletin

The Sun was spotless. Solar activity was at very low levels and is expected to remain so.

The greater than 10 MeV proton flux and the greater than 2 MeV electron flux were at nominal levels during the last 24 hours and are expected to remain so.

No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery.

Solar wind speed started the period near 325 km/s and gradually declined to its current 300 km/s (DSCOVR). Bz undulated between -2 and +2 nT. The direction of the interplanetary magnetic field (phi angle) was mostly in a sunward orientation (negative sector).

Geomagnetic activity was at quiet levels. Geomagnetic conditions are expected to be quiet with an unsettled period possible on 14-15 May due to weak CH wind streams.

Today's estimated international sunspot number (ISN): 000, based on 23 stations.
