Solar flaring activity was at moderate levels over the past 24 hours with a single M4.7-class flare, peak time 10:11 UTC on Jan 25th from the NOAA AR 3190 (beta-delta) near the south-west limb. This region produced several notable C-class flares and remains the largest and most complex active region on the visible solar disc. It is expected to rotate over the west limb over the next day. Isolated low flaring activity was produced nearby the west limb by NOAA AR 3194 (beta) and NOAA AR 3192 (beta), including a C9.6 flare with peak time 04:53 UTC on Jan 25th. The remaining regions on the solar disc are all relatively small and have not shown signs of significant flaring activity. The solar flaring activity is expected to be mostly at low levels over the next 24 hours with possible isolated M-class flaring and minor chances for an X-class flare.

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

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux has been below the1000 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 conditions (ACE and DSCOVR) were indicative of mostly slow solar wind conditions. The solar wind velocity varied around 400 km/s. The interplanetary magnetic field peaked at 8 nT with a minimum Bz of -7 nT. The B field was predominantly in the positive sector (directed away from the Sun). The solar wind parameters could register some enhancements over the next 24 hours with an expected mild high speed stream arrival from a positive polarity coronal hole.

The geomagnetic conditions over the past 24 hours were quiet. Mostly quiet to unsettled conditions are expected for the rest of the day with possible active periods and quiet to active conditions with possible isolated minor storm levels could be expected throughout Jan 26th.
