太陽活動區和耀斑

Solar flaring activity over the past 24 hours was quiet with only one small C-class flares beside the number of bipolar regions on the solar disc visible from Earth. There are currently 10 numbered active regions with alpha or beta magnetic field configurations. The most complex regions are NOAA AR 3451 (beta-gamma) and NOAA AR 3452 (beta-gamma). The solar flaring activity is likely to be at quiet levels over the coming days with C-class flares expected, and a low chance for isolated M-class flares and X-class flaring.

日冕物質拋射

No other Earth-directed Coronal Mass Ejections have been detected in the last 24 hours in the available SOHO/LASCO images.

太陽風

In the last 24 hours, the solar wind conditions near Earth remained slightly under the influence of the solar wind streams associated to 2 small positive polarity coronal holes that crossed the central meridian on October 01 and 02. The total interplanetary magnetic field was ranging between 5.0 nT and 7.3 nT. The Bz-component of the interplanetary magnetic showed mainly negative values with a minimum value of -4.6 nT. The solar wind speed had values varying between 337 km/s and 437 km/s. The solar wind is expected to return to nominal conditions in the next hours.

地磁

The geomagnetic conditions over the past 24 hours were quite to unsettled (K Bel 2-3, Kp-NOAA 2-3) due to the slight enhancement of the solar wind conditions. Quiet to unsettled conditions are expected in the next 24 hours.

質子通量水平

The greater than 10 MeV proton flux was at background levels over the last 24 hours. It is expected to mostly remain at background level, however possible rise of the proton flux cannot be fully excluded due to the current number of complex regions on the disc.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux measured by GOES-16 was below the 1000 pfu threshold. The greater than 2 MeV electron flux is expected remains below the threshold in the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain at normal levels in the next 24 hours.
