太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours. The largest flare was a C1.1 flare (SIDC Flare 7217) peaking on March 15 at 15:09 UTC, which was produced by SIDC Sunspot Group 822 (NOAA Active Region 4395). There are currently 6 numbered regions on the disk. SIDC Sunspot Group 818 (NOAA Active Region 4391) also produced a C1.1 (SIDC Flare 7219), peaking on March 19 at 09:54 UTC. SIDC Sunspot Group 820 (NOAA Active Region 4392, Beta-Gamma magnetic configuration) is the largest region on disk and was growing over the past 24 hours. The other regions are simple and mostly quiet. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares expected and a chance for M-class flares.

日冕物質拋射

No new Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery.

日冕洞

The southern midlatitude extension of the large positive polarity trans-equatorial coronal hole (SIDC Coronal Hole 154) is still crossing the central meridian.

太陽風

Over the past 24 hours, the solar wind parameters reflected the ongoing influence of the high speed stream associated with SIDC Coronal Hole 154. The solar wind speed decreased slightly from around 700 kms to 550 km/s. The total magnetic field was stable around 6nT. Bz had a minimum of -5 nT. The interplanetary magnetic field phi angle was mostly in the positive sector (directed towards the Sun). The solar wind conditions are expected to remain perturbed over the next 24 hours due to the continued influence of the high speed stream of this extended coronal hole.

地磁

Over the past 24 hours, the geomagnetic conditions were at unsettled to active levels globally (NOAA Kp 4) and locally (K BEL 4). Further active conditions are expected over the next 24 hours, due to the ongoing high speed stream influence.

質子通量水平

The greater than 10 MeV proton flux was below the 10 pfu threshold over the past 24 hours. It is expected to remain below this threshold level over 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-18 and GOES-19 satellites, briefly exceeded the 1000 pfu threshold. The greater than 2 MeV electron flux is expected to again exceed the 1000 pfu threshold over the next 24 hours. The electron fluence was at normal to moderate levels and is expected to be at moderate levels for the next 24 hours.
