Solar activity has been low, NOAA ARs 2373 and 2376 have shown little activity, producing 3 C-class flares in the past 24 hours. The largest flares were a C1.4 class flare produced by AR 2376 peaking at 22:51 UT on 01-Jul-2015 and another C1.4 flare produced by AR 2373 peaking at 06:18 UT on 02-Jul-2015. An eruption occurred from beyond the western limb of the Sun at around 14:00 UT on 01-Jul-2015, the eruption produced a full halo CME, which was detected by CACTUS at 14:36 on 01-Jul-2015 with a velocity of 346 km / s. The CME exhibited no on-disk signatures and is believed to be back-sided, occurring close to the west limb. There was a small increase in protons related to the event, but this did not exceed 5 pfu at the Earth.

The solar wind speed has been steadily decreasing over the past 24 hours, from 450 to 400 km / s. The total magnetic field has been relatively stable around 5 - 6 nT, and the Bz component has fluctuated from positive to negative, between +6 and -5 nT over the past 24 hours. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 0-3 over the past 24 hours, similar conditions are expected to persist. There was one CME in the past 24 hours (see details above), which emerged from beyond the West limb, it is not expected to produce any significant activity at the Earth. There is one transient coronal hole currently located in the South, which may enhance solar wind speeds at the Earth in a few days.
