太陽活動區和耀斑

Solar flaring activity was low but frequent during the last 24 hours, with the brightest flares being C2. NOAA Active Region (AR) 3561 (now behind the solar limb) produced most of the activity, followed by NOAA AR 3559 (magnetic configuration Beta-Gamma, Catania sunspot group 43). The C-class flaring activity is expected to continue in the next 24 hours, mostly from NOAA AR 3559 and the three yet- unnamed AR currently turning to Earth's view.

日冕物質拋射

No Earth directed Coronal Mass Ejections (CME) have been observed in the available coronagraph data. Two partial halo CME automatically detected by CATCus as launched yesterday 15:24 UTC and today 03:12 UTC are associated with flaring activity at the East limb and are not expected to be geo-effective.

太陽風

The Solar Wind (SW) conditions of the last 24 hours are typical of the slow wind regime. A glancing blow from the passing of a Coronal Mass Ejection (CME) nearby only caused a very minor effect this morning, as predicted. The SW speed ranged between 330 km/s and 420 km/s, while the total interplanetary magnetic field (Bt) varied between 3 and 11 nT and its North-South component ranged between -3 and 8 nT. The interplanetary magnetic field phi angle changed from mostly being directed towards the Sun yesterday to away from the Sun today. The SW conditions are expected to be affected by the arrival of a High Speed Stream (HSS) within the next 24 hours.

地磁

Geomagnetic conditions were globally and locally quiet (NOAA Kp 1- to 2 and K BEL 1 to 2) during the last 24 hours. They are likely to increase to unsettled or active levels as a High Speed Stream (HSS) is likely to arrive in next 24 hours.

質子通量水平

The greater than 10 MeV proton flux was at nominal 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, as measured by the GOES-16 satellite, was well below the 1000 pfu alert threshold during the last 24 hours and is expected to to remain at this level during the next 24 hours. The 24h electron fluence was at low levels during the past 24 hours and is expected to remain at these levels for the following 24 hours.
