Bulletin

Solar flaring activity was low during the last 24 hours with four C-class flares detected, the brightest being a C7 on 5 July 12:38 UT from NOAA Active Region (AR) 3053. The newly numbered NOAA AR 3052 and 3053 had very significant flux emergence during the last 24 hours and they are expected to produce C-class flares in the next 24 hours. There is also a good chance that NOAA AR 3052 will produce an M-class flare in the next 24 hours.

No Earth-directed coronal mass ejections (CME) 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 remained typical of the slow regime. The SW speed dropped further from 400 to 330 km/s in the last 24 hours. The total magnetic field (Bt) had a maximum of 8 nT, while its Bz component ranged between -6 to 3 nT. The interplanetary magnetic field phi angle was mostly in the negative sector (directed towards the Sun) on 5 July but has turned to mostly positive since. The SW conditions are expected to be affected by the arrival of a High Speed Stream (HSS) in the next 24 hours.

Geomagnetic conditions were quiet globally (Kp 1-2) and moderate locally (K Doubres 1-3) during the last 24 hours. The geomagnetic activity is expected to become moderate both globally and locally in the next 24 hours as a result of the expected HSS.
