Solar activity has been increasing over the past 24 hours. With 6 C-class flares produced from Active Regions (AR) 2373, 2376 and 2378. AR 2378 has rotated into view on the east limb and produced the largest flare, a C5.6 class flare, peaking at 03:05 UT on 2015-Jul-03. A CME can be seen emerging from beyond the north-east solar limb at 18:00 UT on 2015-Jul-02 with a velocity of 440 km / s. The CME is not expected to be geo-effective. The proton numbers have continued to be low and have not exceeded ~1 pfu at the Earth in the past 24 hours. Solar activity may increase in the coming days with the arrival of AR 2378, which appears quite active.
The solar wind speed has been steadily decreasing over the past 24 hours, from 360 to 320 km / s. The total magnetic field has been relatively stable around 3 - 4 nT, and the Bz component has been around 0 nT with some small fluctuations in the past 24 hours. Geomagnetic conditions ranged between Kp index 0-1 (NOAA) and local K index (Dourbes) 0-2 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 north-east solar 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 couple of days.
Today's estimated international sunspot number (ISN): 090, based on 21 stations.
