Solar Active Regions and flaring

The solar flaring activity was low during the last 24 hours with few C-class flares. The strongest reported flare was GOES C2.7 flare which peaked at 11:25 UTC today. During the flare, the source region (AR 3598) of the flare had beta configuration of its photospheric magnetic field. The solar flaring activity is expected to be at low to moderate levels over the next 24 hours with few C-class flares, and a low chance for M-class flares.

Coronal mass ejections

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph observations during last 24 hour.

Coronal holes

A small high latitude northern coronal hole (negative polarity) has crossed the central meridian on Mar 05, and it will not possibly impact the Earth. Another very small equatorial (negative polarity) coronal hole is crossing the central meridian on Mar 05. The solar wind from this coronal hole may enhance the solar wind environment near Earth on Mar 08.

Solar wind

Solar wind parameters are transitioning from fast to slow solar wind regime. The solar wind speed ranged between 350 km/s and 450 km/s. The North-South component (Bz) ranged between -5 and 10 nT. The interplanetary magnetic field has decreased from 12 nT to 5 nT. Slow solar wind conditions are expected to continue over the next 24 hours.

Geomagnetism

Geomagnetic conditions were globally and locally quiet to unsettled conditions (NOAA Kp and K BEL 1 to 3). Quiet to unsettled conditions are expected in the next 24 hours.

Proton flux levels

The greater than 10 MeV proton flux was below the threshold level over the past 24 hours and is expected to remain so for the next 24 hours.

Electron fluxes at geostationary orbit

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was below the threshold level in the last 24 hours. It is expected that this parameter to remain below the threshold level in the next 24 hours. The 24h electron fluence is presently at normal level and is expected to remain so in the coming 24 hours.

Today's estimated international sunspot number (ISN): 112, based on 08 stations.
