Bulletin
Only minor C-class flaring in past 24 h, from NOAA AR 2268. The strongest one was a C3.7 flare with peak at 16:00 UT on January 23. This region will most likely continue to produce C-class flares, with reduced chances of M-class flares. Geomagnetic conditions are quiet. Solar wind is nominal, with speeds of 400 km/s and magnetic field intensities around 5 nT. The fast speed stream from a high latitude coronal hole may influence the Earth in the next 24h, most likely producing active geomagnetic conditions at most.
