太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours with several C-class flares. The largest flare was a C3.4-flare, with peak time 01:46 UTC on Jan 14 2025, from SIDC Sunspot Group 360 NOAA AR 3947 (beta-gamma). There are currently 7 numbered active regions on the visible disk. SIDC Sunspot group 2360 (NOAA AR 3947) is the most complex AR (beta-gamma). The solar flaring activity is expected to be at low levels over the coming day with C-class flares expected and a chance of M-class flares.

日冕物質拋射

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

日冕洞

The large east-west elongated negative polarity equatorial coronal hole (SIDC Coronal Hole 87) is still crossing the central meridian. A high-speed stream from this coronal hole may enhance the solar wind environment near Earth on Jan 16.

太陽風

Over the past 24 hours, the solar wind speed has increased temporarily to 495 km/s, then returned back to around 411 km/s.The interplanetary magnetic field varied between 6 nT and 8 nT, with the Bz reaching a minimum value of -6 nT.

地磁

Geomagnetic conditions were globally and locally quiet to unsettled (Kp 3 and K Bel 3). Quiet to active conditions with possible isolated minor geomagnetic storm levels are expected for the next 24 hours.

質子通量水平

The greater than 10 MeV proton flux remained below the 10 pfu threshold 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 alert threshold, and is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
