Solar flaring activity over the past 24 hours was at very low levels no significant flaring activity. There are three numbered sunspot regions on the visible disc and a few simple unnumbered ones in the south- eastern quadrant. NOAA 3040 (beta) is still the largest active region on the visible disc, but has remained stable and inactive. NOAA 3042 has decayed into plage. NOAA 3045 and the newly numbered active region NOAA 3046 have shown some decay and are now classified as magnetic type alpha. The X-ray flaring activity over the next 24 hours is expected to be at very low to low levels.

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 in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux return to background levels, well below the 1000 pfu threshold and is expected to remain below the 1000 pfu threshold over the next 24 hours. The 24h electron fluence was at moderate levels and is expected to decrease towards nominal levels over the next 24 hours.

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) registered the arrival of a slow ICME. This could be a late arrival of the slow partial halo CME related to the filament eruption in the south-western quadrant on June 26th. The arrival was preceded by a minor discontinuity around 09 UTC on July 1st, followed by increase in density, smooth rotation in the magnetic field around 23:30 UTC same day and the magnitude of the interplanetary magnetic field reaching almost 14 nT throughout July 2nd. The north-south Bz component registered expended period with negative values, reaching -13 nT early UTC this morning. The solar wind speed over the past 24 hours showed very mild fluctuations in the range of 316 km/s to 366 km/s. The solar wind parameters are expected to remain slightly elevated throughout the day and return to background slow solar wind conditions by tomorrow. A positive polarity coronal hole has crossed the central meridian and the related high speed stream could reach Earth on July 5th.

The geomagnetic conditions over the past 24 hours registered a couple of active periods and an isolated minor storm in response to the ICME arrival. Mostly quiet to unsettled geomagnetic conditions are expected over the next 24 hours with possible isolated active periods under the waning influence of the ICME.
