Solar activity was at low levels over the past 24 hours. There is one numbered Active Region (AR) on the solar disk, NOAA AR 2797 (alpha), which remained stable. NOAA AR 2799 (alpha) has now rotated over the west solar limb. Solar activity is expected to remain at low levels, with a low probability of a C-class flare.

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux was enhanced but remained mostly just below the 1000 pfu threshold during past 24 hours, until 11:40 UT when it briefly crossed the threshold. The electron flux is expected to remain enhanced and is likely to cross this alert threshold again during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to be at nominal to moderate levels over the next 24 hours.

Over the past 24 hours, the solar wind speed remained elevated with values ranging between 480 and 580 km/s (DSCOVR). The total magnetic field strength fluctuated around 5 nT. Bz had a minimum value of -5 nT. The interplanetary magnetic field was predominantly directed towards the Sun (phi angle in the negative sector). Over the next 24 hours, the solar wind speed is expected to gradually decrease as the influence from the high- speed stream that is currently influencing the Earth continues to wane.

Geomagnetic conditions were at quiet to unsettled levels (NOAA Kp and local k Dourbes recorded values between 2-3 and 1-3, respectively.) Geomagnetic conditions are expected to be at quiet to unsettled levels for the next 24 hours.
