Bulletin

Solar flaring activity was at moderate levels over the past 24 hours with several C-class flares and an isolated M flare observed. The largest flare observed was an M1.2 flare, peaking at 04:31 UT, originating from a region about to rotate onto the disk over the east limb (N15E80). There are four other numbered active regions on disk which were mostly stable. The flaring activity is expected to be at low levels with C-class flares expected, M-class flares remain possible and there is chance for an X-class flare.

No Earth directed Coronal Mass Ejections (CMEs) have been observed in the available coronagraph data.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2MeV electron flux was below the 1000 pfu threshold and is expected to remain so over the next 24 hours. The 24h electron fluence was at normal levels and is expected to be at normal levels over the next 24 hours.

The Earth is currently under the influence of a high-speed stream. The solar wind increased from 475 to around 580 km/s. The total magnetic field was stable around 6nT. The interplanetary magnetic field phi angle was predominantly in the positive sector (directed away from the Sun). The solar wind conditions are expected to remain enhanced for the next 24 hours due to the continued influence of the high speed stream.

Geomagnetic conditions were quiet over the past 24 hours (NOAA Kp and Local K-Dourbes 1-2). Geomagnetic conditions are expected to be mostly quiet over the next 24 hours with unsettled and active intervals possible.
