The solar flaring activity was at very low levels with only B-class flares reported in the past 24 hours. NOAA ARs 3151 and 3152, the two largest regions on disk (magnetic type beta), have shown some minor growth but produced only B-class flares. Solar flaring activity is expected to be at very low levels, with a low chance of C-class flares.

No Earth directed Coronal Mass Ejections (CMEs) were detected in the available coronagraph imagery.

In the past 24 hours the greater than 10 MeV proton flux was below the minor-storm warning threshold and is expected to remain so. The greater than 2 MeV electron flux crossed the 1000 pfu threshold during the last 24 hours. The 24h electron fluence was at normal to moderate levels over the past 24 hours before decreasing again. The 24h electron fluence is expected to be at normal levels in the next 24 hours.

On November 28, a large trans-equatorial positive polarity coronal hole began to transit the central meridian.

The solar wind parameters reflected the influence of a high-speed stream. The solar wind speed increased from 400 to 620 km/s. The interplanetary magnetic field magnitude gradually increased from 5 to above 10 nT. The magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). The solar wind speed is expected to continue to be enhanced over the next days, due to the ongoing influence of the high-speed streams associated with multiple positive polarity coronal holes.

Geomagnetic conditions were active, with an isolated interval of minor storm conditions globally, (NOAA Kp 2-5, local K-Dourbes 1-4). Geomagnetic conditions are expected to be unsettled to active on Nov 28 to Nov 30, with further intervals of minor storm conditions possible as the current high- speed stream continues to influence the Earth and further enhancements are expected.
