Solar flaring activity remained at very low levels over the past 24 hours. Currently there are six numbered regions on the visible solar disc and a new unnumbered active region close to the northeast. Regions NOAA 3068 (beta) and NOAA 3072 (beta) produced some high B-class flaring, but overall remained stable and quiet. NOAA 3073 (beta) remained inactive, as well as NOAA 3071 (alpha) and NOAA 3074 (alpha). NOAA 3075 (beta) was newly numbered close to the northeast limb. It remained quiet and inactive. The flaring activity over the next 24 hours is expected to be at very low levels with low chances for isolated C-class flaring.

A type II radio burst was detected at 02:26 UTC on Aug 7th. There is no coronagraph data at this time to estimate any possible impacts. SDO AIA data suggests that the emission could be rated to post-flaring activity from NOAA 3068 in which case Earth-directed ejecta is very unlikely. 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 has been below the1000 pfu threshold and is expected to remain so. The 24h electron fluence was at nominal levels and is expected to remain so over the next 24 hours.

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) have registered an expected high speed stream arrival. The solar wind velocity has gradually increased from 316 km/s to 455 km/s. The interplanetary magnetic field moderately increased up to 13.7 nT with a minimum Bz of -10.7 nT. The B field switched orientation transitioning from the negative to the positive sector (directed away from the Sun) in accordance with the polarity of the geo-effective coronal hole. The solar wind parameters are expected to remain enhanced over the next 24 hours and get further elevated with the expected arrival of a second high speed stream on Aug 08th.

The geomagnetic conditions over the past 24 hours were quiet to unsettled. Quiet to active geomagnetic conditions are expected for the next 24 hours with chances for isolated minor storms.
