Solar flaring activity was at very low levels. Active Region (AR) 2762 produced a B-flare at 12:17 on Apr 30. AR 2760 and newly numbered AR 2763 located at N32E12 were inactive over the period. Solar flaring activity is expected to remain at very low levels. A small patchy negative polarity equatorial coronal hole began to transit the central meridian on May 01.

No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery in the last 24 hours.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels for the next 24 hours. The greater than 2 MeV electron flux was between nominal and moderate levels over the past 24 hours and is expected to be at nominal to moderate levels over the next 24 hours.

The solar wind speed near Earth varied between 270 km/s to 320 km/s (DSCOVR). The total magnetic field oscillated around 4 nT for the first half of the period but showed a gradual increase from 03:20 UT May 01 to a maximum value of 8 nT. Bz was mostly positive until 03:20 UT when it became negative for an extended duration with values down to -6 nT. The Interplanetary Magnetic Field (IMF) phi angle was predominantly in the negative sector (directed towards the Sun), deviating into the positive sector during the period of slightly enhanced negative Bz. Predominantly background solar wind conditions are expected for May 01 - 03. The filament eruption observed on April 27, that possibly had an Earth directed component, may produce a slight enhancement in solar wind parameters at Earth on May 02.

Geomagnetic conditions were quiet to unsettled (local K Dourbes and NOAA Kp recorded values between 0-2 and 0-3, respectively). Quiet to unsettled geomagnetic conditions are expected for May 01 - 03, with the possibility of an isolated active interval.
