Aktywne obszary słoneczne i rozbłyski

Solar flaring activity over the past 24 hours was at low levels. The largest flare was a C9.6-flare, with peak time at 03:25 UTC on January 10, associated with NOAA AR 3538 (beta). There are currently 11 numbered active regions on the visible disk. NOAA AR 3536 (beta-gamma) is the most magnetically complex region on disk. Together with NOAA AR 3538, NOAA AR 3539 (beta), and NOAA AR 3546 (beta), it has produced most of the flaring activity in the last 24 hours. The solar flaring activity is likely to be at moderate levels over the coming days with C-class flares expected and M-class flares possible.

Koronalny wyrzut masy

Based on currently available coronagraph images, one partial-halo CME was detected in the past 24 hours (first detection by SOHO/LASCO C2 around 15:12 UTC on January 09). The CME seems to be associated with the eruption of two filaments in the south-east quadrant of the solar disk. No clear Earth-directed component has been identified, and at most we expect a glancing blow in about 4 days. Further analysis to determine any Earth-directed CME component is on-going.

Wiatr słoneczny

Slow solar wind conditions were recorded over the past 24 hours. The solar wind speed as measured by ACE ranged between 360 km/s and 435 km/s, although we report gaps in the ACE data between 22:10 UTC on January 09 and 00:32 UTC on January 10, and between 02:34 UTC and 07:07 UTC on January 10. The total interplanetary magnetic field fluctuated between 4 nT and 9 nT, with the Bz (north-south) component reaching a minimum value of -8 nT. The phi-angle remained mainly in the positive sector (away from the Sun). In the next 24 hours, we expect similar slow solar wind conditions.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were globally and locally quiet (Kp 2 and K Bel 2). Quiet to unsettled conditions are expected in the next 24 hours due to possible prologued negative Bz conditions in the solar wind.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was still slightly enhanced but below the 10 pfu threshold, and it continues to gently decline. The proton flux is expected to continue to decrease in the coming days and reach the background level soon. Due to the number of complex regions currently on the disk, we cannot exclude the possibility of new proton events in the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV GOES 16 electron flux was below the 1000 pfu threshold and is expected to remain so in the next 24 hours. The 24h electron fluence was at nominal level and is expected to remain so in the next 24 hours.
