Solar activity was at very low levels over the last 24 hours. There are five Active Regions (AR) visible on the Sun. NOAA AR 2898 and 2900 (beta magnetic field configuration) have shown signs of decay. NOAA AR 2901 (alpha magnetic field configuration) remained stable. Two new active region have also emerged over the period, NOAA AR 2902 (N18E05) and NOAA AR 2903 (S17E53). Solar activity is expected to be at very low levels, with a chance for a C-class flare.

A Coronal Mass Ejection (CME) associated with the filament eruption observed lifting off in the southern hemisphere on Nov 29 is very narrow and directed to the south and is not expected to impact Earth. No Earth directed CMEs have been detected in the available coronagraph imagery.

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

The solar wind speed (DSCOVR) ranged between 330 to 380 km/s. The total magnetic field ranged from 1 nT to around 5 nT. The Bz varied between -3 and +3 nT. The interplanetary magnetic field phi angle switched to the positive sector (directed away from the Sun) from 04 UT. The solar wind speed is expected to continue to reflect a slow solar wind regime on Nov 30, with slight enhancements possible from Dec 01, due to the interaction with the patchy coronal hole that passed the central meridian on Nov 28.

Geomagnetic conditions were at quiet levels (NOAA Kp and K-BEL recorded values of 0-2). Geomagnetic conditions are expected to be quiet on Nov 30, with unsettled conditions probable on Dec 01.
