太陽活動區和耀斑

Solar flaring activity was at low levels in the past 24 hours. The largest flare was a C1.5 flare, peaking at 07:09 on Oct 23, associated with NOAA AR 3468. Other regions on the disc have simple configuration of their photospheric magnetic field (alpha and beta) and did not show any significant flaring activity. The solar flaring activity is expected to be at very low to low levels over the next 24 hours with a chance for C-class flares.

日冕物質拋射

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

日冕洞

A small positive polarity equatorial coronal hole transited the central meridian today, on Oct 23.

太陽風

The solar wind parameters were indicative of ongoing weak transient magnetic structures. The interplanetary magnetic field ranged between 6 and 9 nT. The solar wind speed increased from 290 to 350 km/s. The southward component of the interplanetary magnetic field fluctuated between -9 nT and 8 nT. Similar conditions are expected in the next 24 hours, with a chance of a week enhancement on Oct 23 – Oct 24 due to high- speed stream influence from the small negative polarity coronal hole, which crossed the central meridian on Oct 19.

地磁

Geomagnetic conditions were quiet to unsettled (NOAA Kp: 1 to 3 and K-BEL: 1 to 3). Geomagnetic conditions are expected to be at quiet to unsettled levels with a chance for isolated active periods on Oct 23-24 due the influence of the high speed stream.

質子通量水平

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so over the next days.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux remained below the 1000 pfu threshold as measured by GOES 16. It is expected to remain below this threshold over the next days. The 24 hour electron fluence was at normal levels and is expected to remain so.
