太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours. NOAA Active Region (AR) 3492 (Catania sunspot group 58) was possibly the source of the strongest flare over the past 24 hours, the C8.9 flare, which peaked at 22 November 06:28 UTC. NOAA AR 3489 (Catania sunspot group 52) has remained complex, with low level flaring activity.

日冕物質拋射

A number of filament eruptions have been observed. A CME as seen in Lasco C2 on 22 November 06:48 UT is believed to be associated with the filament eruption with source region about S20E40, occurring on 22 November 06:12 UT. The CME is currently being investigated for any minor chance of a glancing blow.

日冕洞

The southern negative polarity coronal hole will be in a geo-effective position over the next 24 hours. The mid latitude coronal hole positive coronal hole should cross central meridian on about 23 November.

太陽風

Earth is under the influence of the high speed stream from the positive polarity northern coronal hole. The interplanetary magnetic field reached occasionally 15 nT  and in the positive sector (directed away from the Sun).. The north-south component neared down to -14 nT, but was mostly variable. Solar wind speed reached a maximum of 595 km/s and remains elevated. High speed stream are expected to continue over the next 24 hours, albeit with less severity.

地磁

Geomagnetic conditions reached minor storm conditions(NOAA Kp 5) over the past 24 hours. It is expected for geomagnetic conditions to reach active levels over the next 24 hours, due to high-speed stream arrivals.

質子通量水平

Over the past 24 hours the greater than 10 MeV GOES proton flux was below threshold and is expected to remain so over the next 24 hours.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux was below the 1000 pfu threshold, as measured by GOES 16. It is expected to increase towards moderate levels in the next 24 hours. The 24 hour electron fluence was at normal levels, it is expected too increase towards moderate levels for the next 24 hours.
