太陽活動區和耀斑

Solar flaring activity was moderate over the past 24 hours, with 5 M-class flares. The largest flare was a M3.7 flare (SIDC Flare 2647), peaking on November 18 at 12:53 UTC, produced by newly numbered SIDC Sunspot Group 298 (NOAA Active Regions 3901), which also produced multiple other low-level M-class flares. SIDC Sunspot Group 288 (NOAA Active Region 3889), now near the west limb, also produced an M1.1 flare (SIDC Flare 2633) peaking on November 19 at 00:00 UTC. The solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares likely and a chance for X-class flares.

日冕物質拋射

No Earth-directed coronal mass ejections (CMEs) have been detected in the available coronagraph imagery over the past 24 hours.

太陽風

Over the past 24 hours the solar wind conditions predominantly reflected a slow solar wind regime. The interplanetary magnetic field continued to be slightly elevated, ranging between 5 and 9nT, with a minimum Bz of -8 nT. The solar wind speed decreased from 470 km/s to around 340 km/s The interplanetary magnetic field phi angle remained predominantly in the positive sector (directed towards the Sun). Slow solar wind conditions are expected to continue over the next 24 hours.

地磁

The geomagnetic conditions over the past 24 hours were quiet. Quiet to unsettled geomagnetic conditions are expected for the next 24 hours.

質子通量水平

Over the past 24 hours the greater than 10 MeV GOES proton flux was below the 10 pfu threshold. The greater than 10 MeV GOES proton flux is expected to continue to be below this threshold over the 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 was slightly elevated but remained below the 1000 pfu threshold briefly and is expected to remain below this threshold over the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so in the next 24 hours.
