太陽活動區和耀斑

Solar flaring activity over the past 24 hours was at low levels with several B-class flares and few C class flares. The solar flaring activity is likely to be at low levels over the coming days with C-class flares and a very low possibility of M-class flares.

日冕物質拋射

Based on currently available coronagraph images several coronal mass ejections (CMEs) were observed. No Earth directed coronal mass ejections have been identified in the last 24 hours.

日冕洞

The small midlatitude coronal hole in the northern hemisphere (with positive magnetic polarity) is now on the solar meridian. It’s a high-speed stream may impact the solar condition near Earth today and tomorrow.

太陽風

Slow solar wind conditions were recorded over the past 24 hours. The solar wind speed as measured by DSCOVR ranged between 360 km/s and 500 km/s. The total interplanetary magnetic field was below 8 nT, and the Bz (north-south) component fluctuating between -7 nT and 5 nT. Slow solar wind conditions are expected for the next 24 hours. Then, influences from the high speed stream coronal hole may be observed in the solar wind parameters.

地磁

The geomagnetic conditions over the past 24 hours were mostly quiet with some unsettled periods (NOAA-Kp and K-Bel 1-3). Mostly quiet conditions are expected in the next 24 hours. Then, unsettled to active condition may occur in response to the influences from the high speed stream coronal hole.

質子通量水平

The greater than 10 MeV protons flux where at background levels. It is expected to be at background levels in the next 24 hours.

地球靜止軌道上的電子通量

The greater than 2 MeV GOES 16 electron flux was below the 1000 pfu threshold and is expected to remain so in the next 24 hours. The 24h electron fluence was at nominal level and is expected to remain so in the next 24 hours.
