太陽活動區和耀斑

Solar flaring activity was moderate over the past 24 hours. NOAA AR 3490 was the source of the flare with the highest output in X-ray over the past 24 hours, the C5.5 flare, which peaked at 24 November 22:20 UT.

日冕物質拋射

A CME as seen in Lasco C2 on 24 November 10:00 UT is believed to be associated with the M1.1 flare with source region 3489, occurring on 24 November 09:34 UT. The CME has the potential of a glancing blow early 27 of November.

日冕洞

The mid latitude positive polarity coronal hole is in geo- effective position.

太陽風

A shock in the solar wind at 07:55 UTC on November 15 marks the arrival of the ICME from November 22. The speed jumped from 490 km/s to 540 km/s and the interplanetary magnetic field from 9 to 14 nT. Further high speed stream influences and a possible second ICME arrival (from CME occurring at 22 November 21:12UT) can be expected over the next 24 hours.

地磁

The arrival of the ICME from November 22 created minor storm geomagnetic conditions globally (Kp 5) and active conditions locally (K_Bel 4). A combination of influences from a high speed stream and a possible second ICME arrival (from CME occurring at 22 November 21:12UT) can be expected over 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 threshold and is expected to most likely remain so over the next 24 hours, but keeping in mind the presence of multiple magnetically complex regions on disk.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux crossed the 1000 pfu threshold on 24 November 14:15UT, as measured by GOES 16. It is expected to be at moderate levels in the next 24 hours. The 24 hour electron fluence was close to moderate levels, it is expected to be about moderate levels for the next 24 hours.
