太陽活動區和耀斑

Solar flaring activity has been quite over the past 24 hours with few C-class flares. The larger flare was a C5.2-class flare produced by NOAA AR 3395 (Catania sunspot group 14) and was peaking at 23:52 UTC on August 12. The other regions did not show any significant flaring activity. Solar flaring activity is expected to remain quite over the next 24 hours with a high probability of C-class flare and a small chance of M-class flares.

日冕物質拋射

No coronal mass ejection (CME) with an Earth- directed component was identified in the SOHO/LASCO-C2 coronagraph images over the past 24 hours.

太陽風

The solar wind parameters showed nominal levels over the past 24 hours. The solar wind speed was ranging from 350 km/s to 450 km/s. The total interplanetary magnetic field was below 5.9 nT. The north-south component was fluctuating between -4.7 nT and 4.8 nT. The solar wind conditions are expected to remain as such for the next 24 hours.

地磁

Geomagnetic conditions were mostly quiet with some short unsettled periods (NOAA Kp 1-2, K Belgium 1-3) over the past 24 hours. Mostly quiet conditions with possible short unsettled periods are expected for the next 24 hours.

質子通量水平

The greater than 10 MeV proton flux was at background levels over the past 24 hours and is expected to remain so for the next 24 hours.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux was close to the level of the 1000 pfu alert threshold for a short period, and is expected to remain close or just below threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
