Bulletin

Solar flaring activity was low during the last 24 hours with two C-class flares detected from NOAA Active Regions (AR) 3040 and 3046. There are numerous AR on the visible side of the solar disk, however, they are relatively small with simple magnetic configuration. NOAA AR 3040 will disappear behind the solar limb in the next 24 hours. NOAA AR 3046 lost some of its magnetic complexity during the last 24 hours. There is a small chance of low C-class activity during the next 24 hours, mostly from NOAA AR 3046.

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 over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold and is expected to remain below this threshold during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so.

During the last 24 hours, the Solar Wind (SW) conditions are affected by the arrival of a disturbance. The SW speed gradually increased from 300 to 420 km/s in the last 24 hours. The total magnetic field (Bt) ranged between 6 and 20 nT and its Bz component varied between -13 and 18 nT, during the past 24 hours. The interplanetary magnetic field phi angle was mostly in the negative sector (directed towards the Sun) over the last 24 hours. An interaction region and possibly a High Speed Stream (HSS) is expected during the next 24 hours as the result of the Coronal Hole (CH) crossing of 1 July.

Geomagnetic conditions reached minor storm levels globally (Kp 2-5) and active levels locally (K Doubres 4 between 07:00 and 11:00 UT) during the last 24 hours. Active to minor storm levels are expected in the next 24 hours both globally and locally.
