Solar Active Regions and flaring

Solar flaring activity over the past 24 hours was at moderate levels, with one M-class flares recorded. The largest flare was a M1.0-flare, with peak time 23:15 UTC on July 06 associated with active region NOAA AR 3738 (beta-gamma-delta). There are currently 8 numbered active regions on the visible disk. NOAA AR 3738 (beta-gamma- delta) was the largest and most magnetically complex regions on disk. Most of the flaring activity in the last 24 hours came from NOAA AR 3738 (beta- gamma-delta) and NOAA AR 3729 (beta). NOAA AR 3733 and NOAA AR 3729 have started to rotate over the west limb. The solar flaring activity is likely to be at moderate levels over the coming days with C-class flares expected, M-class flares likely and a small chance for an X-class flare.

Coronal mass ejections

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

Coronal holes

An equatorial positive polarity coronal hole is crossing the central meridian. A high-speed stream emanating from this coronal hole may impact the earth on July 10.

Solar wind

Slow solar wind conditions were recorded over the past 24 hours. The solar wind speed varied within 309 – 362 km/s. The interplanetary magnetic field varied between 2 nT and 6 nT, with the Bz reaching a minimum value of -5 nT. The phi-angle was mainly in the positive sector (directed away from the Sun) with periods in the negative sector. Slow solar wind conditions are expected in the next 24 hours.

Geomagnetism

Geomagnetic conditions were globally quiet (Kp 1-2) and locally quiet to unsettled (K_Bel 1-3). Quiet to unsettled conditions are expected in the next 24 hours.

Proton flux levels

Over the past 24 hours the greater than 10 MeV GOES proton flux was at background levels and is expected to remain so over the next days.

Electron fluxes at geostationary orbit

The greater than 2 MeV electron flux measured by GOES 16 was below the 1000 pfu threshold and is expected to remain so in the upcoming days. The 24h electron fluence was at nominal level and is expected to remain so in the next days.

Today's estimated international sunspot number (ISN): 126, based on 09 stations.
