太陽活動區和耀斑

The solar flaring activity was low during the last 24 hours with several C-class flares, most of them produced by NOAA Active Region (AR) 3599. The strongest reported flare was GOES C6.3 flare which peaked at 12:07 UTC on Mar 07. During the flare, the source region (AR 3599) of the flare had beta-gamma 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 several C-class flares, and a chance for M-class flares.

日冕物質拋射

A faint and patchy coronal mass ejections (CME) was first observed on NW limb in SOHO/LASCO-C2 images at 14:00 UTC on Mar 07. It was associated with multiple C-class flares from the NOAA AR 3599 and the EUV wave. This slow and weak CME originates from the centre of the disk, possibly with its Earth-directed compenents may impact the Earth on Mar 13. No other Earth directed component of Coronal mass ejection (CME) has been identified in the available coronograph imagery.

太陽風

Over the past 24 hours, the solar wind parameters were disturbed under the influence of high speed streams (HSSs) from the negative polarity coronal hole which started to cross the central meridian on Mar 05. The solar wind speed ranged between 350 km/s to 550 km/s. The North-South component (Bz) ranged between -7 and 9 nT. The interplanetary magnetic field ranging from 1 nT to 10 nT. Solar wind parameters may continue to enhance if the shock driven by coronal mass ejection (CME), observed at 21:24 UTC on Mar 5, arrives at Earth.

地磁

Geomagnetic conditions were globally at quiet to unsettled conditions (NOAA Kp 1 to 3) and at locally quiet to active conditions (K BEL 1 to 3), due to the arrival of the high speed streams originating from small equatorial (negative polarity) coronal hole, which started to cross the central meridian on Mar 05. In the next 24 hours, active to minor storm conditions are expected if the shock driven by coronal mass ejection (CME), observed at 21:24 UTC on Mar 5, arrives at Earth.

質子通量水平

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.

地球靜止軌道上的電子通量

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.
