Solar activity has been quiet in the last 24 hours with the background X-ray flux steady around the B2 level. Only a couple of minor B flares have occurred. The largest was a B3.4 flare peaking around 8:47 UT associated with the unnumbered active region that is about to turn onto the visible solar disc from behind the East limb. There are currently only three active regions on the solar disc. NOAA AR 2018 and 2020 are stable alpha regions while the beta region 2019 does show signs of further development. No significant CME's were reported. Quiet conditions are expected to continue with only a slight chance on flaring at C level. The all quiet alert is presently maintained but this may need to be revised if NOAA AR 2019 continues to grow and depending on the nature of the active region(s) that are turning onto the disc from behind the East limb. Solar wind speed remained at low levels around the 280 km/s, while the interplanetary magnetic field increased to around the 6 nT level with Bz varying and currently reaching levels of around -4nT. Geomagnetic conditions were quiet with local K Dourbes and NOAA Kp in the 0-2 range. Quiet conditions are expected to continue although some influence of a coronal hole high speed stream can possibly cause enhanced solar wind conditions and associated unsettled geomagnetic conditions in the next 24 to 48 hours.
