太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours, with more than 10 C-class flares identified. SIDC Sunspot Group 553 (NOAA Active Region [AR] 4140, Beta magnetic configuration), SIDC Sunspot Group 555 (NOAA AR 4141, Beta magnetic configuration), and NOAA AR 4142 (Beta magnetic configuration) produced most of the activity. More C-class flaring is expected in the next 24 hours, with a small chance of an isolated M-class flare.

日冕物質拋射

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours.

太陽風

During the past 24 hours the Solar Wind (SW) conditions continued to be affected by the the High Speed Stream (HSS) that arrived on 11 July and is associated with SIDC Coronal Hole 104 (positive polarity). The SW speed was initially at 660 km/s level, dropped to 480 km/s but now features an increase to around 550 km/s. The interplanetary magnetic field (B) varied between 3 and 8 nT and its North-South component (Bz) fluctuated between -6 and 6 nT. The fast SW conditions are expected to persist in the next 24 hours.

地磁

The geomagnetic conditions registered globally and locally quiet to active levels (NOAA Kp 2- to 4- and K BEL 1 to 4). In the next 24 hours they are expected to remain at the same level both globally and locally.

質子通量水平

The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at background levels over the past 24 hours and is likely to remain so in the next 24 hours.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux, as measured by GOES 19, was below but close to the 1000 pfu alert threshold. It is expected to increase in the next 24 hours and probably exceed the alert threshold. The 24-hour electron fluence was at normal levels during the past 24 hours. It is expected to increase but remain at normal levels in the next 24 hours. However, there is chance to register moderate levels in the next 24 hours.
