太陽活動區和耀斑

Solar flaring activity was moderate over the past 24 hours, as an M3.9 (SIDC flare 7259) was detected on 26 Mar at 06:23 UTC. It was produced by SIDC Sunspot Group (SG) 832 (NOAA Active Region [AR] 4403) despite having a Alpha magnetic configuration. The same SG also produced three C-class flares at the second half of 25 Mar. SIDC SG 834 is another region of interest as it also produced three C-class flares, although most of it is behind the East limb. Its brightest flare was SIDC flare 7267, a C5 emitted on 26 Mar at 08:47 UTC. It is most likely a much brighter flare, but obscured by the solar limb. Further isolated M-class flares are likely in the next 24 hours, either from SIDC SG 832 or 834.

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 returned to a slow SW regime, as the effects of the High Speed Stream diminished during the last 24 hours. The SW speed decreased from 600 to 400 km/s, the interplanetary magnetic field (B) ranged between 3 and 8 nT, and its North-South component (Bz) varied from -5 nT to 7 nT. A glancing blow from SIDC CME 642 (launched on 22 Mar 23:54 UTC) has a chance of arrival in the next 24 hours, but is expected to have a minor effect.

地磁

The geomagnetic conditions were globally (NOAA Kp) and locally (K BEL) quiet to unsettled during the past 24 hours. They are expected to remain at quiet to unsettled level during the next 24 hours.

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 and ranged between 1000 and 10000 pfu. A small drop is expected in the next 24 hours, however it is likely that the electron flux will remain above the alert threshold level. The electron fluence decreased fro high to moderate levels on 25 Mar at 19:35 UTC. It is likely to remain at moderate levels in the next 24 hours.
