Solar activity has remained quiet with background X-ray flux close to the B2 level and an occasional moderate B flare (A B5.7 flare from Catania group 22 / NOAA AR 2121 peaking at 5:42 UT and a B5.5 flare from Catania group 20 / NOAA AR 2019 peaking at 7:42 UT). Without significant further development of the active regions presently on disc, quiet solar conditions are expected to continue, and the all quiet alert is maintained. A partial halo CME with an angular width of close to 180 degrees (underestimated by Cactus as 118 degrees) was visible in SOHO/LASCO C2 from 18:00UT July 22 onwards. The mass was expelled in north-western direction from the Sun Earth line. Coronal imagery (PROBA2/SWAP, SDO/AIA, as well as STEREO A EUVI) shows the event to originate from at or just around the western limb at a latitude of around 30 degrees North. Consequently no influence on Earth is expected. Solar wind speed has dropped gradually from its slightly enhanced values at the start of the reporting period (around 350 km/s) to just over 300 km/s presently. The total magnetic field was within the 3-5nT range with variable Bz within the +/-4nT range. Geomagnetic conditions were mostly quiet (NOAA Kp 1-2) with a short period of local unsettled conditions just after UT noon July 22 (K Dourbes 3 returning to 2 afterwards and 0-1 presently). Nominal solar wind conditions and associated quiet geomagnetic conditions are expected to continue over the next days.
