公告

Solar flaring activity was at low level in the past 24 hours with several C-class flares being detected. The X-ray flux background remained at the C level. The largest flare was a C8.3 flare, peaking at 10:50 UTC on Jan 22, associated with active region NOAA 3192 (beta-gamma class). Active region NOAA 3190, that gained complexity from beta-gamma to beta-gamma- delta class, produced only two C-class flares. Active region NOAA 3195 decayed into a plage. Active regions NOAA 3184 and NOAA 3186 rotated over the west solar limb. The solar flaring activity over the next 24 hours is expected to continue at background C-class flaring with isolated M-class flares likely and a chance for X-class flares.

No Earth-directed coronal mass ejection (CME) were detected in the available coronagraph imagery over the past 24 hours.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours but could become enhanced over the next 24 hours with chances of reaching minor radiation storm levels. The greater than 2 MeV electron flux has been below the 1000 pfu threshold and is expected to remain so. The 24h electron fluence was at nominal levels and is expected to remain so over the next 24 hours.

Over the past 24 hours, the solar wind speed showed a gradually decreasing trend, decreasing from 500 km/s to values around 430 km/s. The interplanetary magnetic field magnitude was was between 4 nT to 7 nT. The Bz ranged between -6 to 4 nT. The solar wind speed is expected to continue to gradually decrease over the next 24 hours, as the influence of the HSS wanes.

The geomagnetic conditions over the past 24 hours were quiet to unsettled. Quiet to unsettled conditions are expected over the next 24 hours with remaining minor chances for isolated active periods.
