Solar activity was at low levels. NOAA Active Region (AR) 2840, which has already rotated over the west limb, produced a C6 and a c7 flare, peaking at 0755UT and 1031UT, respectively. NOAA AR 2839 continued to decay and was inactive. A new bipolar sunspot group (Catania 14) has rotated onto the solar disk (S18E70) but is so far inactive. A new active region is also expected to rotate over the east limb over the next day. A Solar activity is expected to be very low over the next 24 hours with a low probability of C-class flares, particularly while AR2840 remains just beyond the solar limb.

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery.

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 level during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so.

The Earth is currently under the influence of the slow solar wind. The solar wind speed varied between 300 and 340 km/s. The total magnetic field had a maximum of 6 nT. The Bz varied between -6 and +3 nT. The interplanetary magnetic field phi angle was predominantly in the positive sector (directed away from the Sun). The solar wind conditions are expected to continue to reflect a slow solar wind regime for the next 24 hours, with a possible slight enhancement in the solar wind speed due to the influence from a small positive polarity coronal hole that crossed the central meridian on Jul 06.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 1-2 and local K Dourbes 0-3) over the past 24 hours. Geomagnetic conditions are expected to be quiet to unsettled over the next 24 hours.
