太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours, with four C1 flares identified. SIDC Sunspot Group (SG) 831 (NOAA Active Region [AR] 4402, Beta magnetic configuration) produced two of those flares, while SIDC SG 828 (NOAA AR 4398, Beta magnetic configuration) and SIDC SG 826 (NOAA AR 4400, Beta-Gamma-Delta magnetic configuration) produced the rest. More C-class flaring activity is expected in the next 24 hours.

日冕物質拋射

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

太陽風

The Solar Wind (SW) conditions remain affected by a High Speed Stream (HSS) during the past 24 hours. However, the effect is waning as the SW speed gradually felt from 730 to as low as 570 km/s. The interplanetary magnetic field (B) ranged from 2 nT to 6 nT, and its North-South component (Bz) varied from -6 nT to 4 nT. For the next 24 hours the HSS effect is expected to cease and the SW gradually return to a slow SW regime.

地磁

During the past 24 hours the global geomagnetic conditions first reached minor storm levels (NOAA Kp 5 at 15:00 - 18:00 UTC and 5- at 12:00 - 15:00 UTC) and then decreased to unsettled to active levels. The local conditions followed a similar pattern during the same period of time with K BEL 5 at 15:00 - 21:00 UTC and quiet to active levels for the rest of the past 24 hours. Further decrease of the K indices is expected in the next 24 hours, as active to quiet conditions are expected to prevail.

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

During the past 24 hours, the greater than 2 MeV electron flux as measured by GOES 19 was above the 1000 pfu alert threshold, with a peak value of 7000 pfu. For the rest of the past 24 hours a further increase is expected. During the past 24-hours the electron fluence increased but remained at moderate levels. In the next 24 hours it is expected to increase further and probably reach high levels.
