太陽活動區和耀斑

Solar flaring activity was low over the past 24 hours, with only a C1.0 flare from the east limb (SIDC Flare 7063) peaking at 07:33 UTC on February 24. There are currently no numbered active regions on the solar disk. SIDC Sunspot Group 799 has decayed into a plage. The solar flaring activity is expected to be low over the next 24 hours, with C-class flares unlikely.

日冕物質拋射

No Earth-directed Coronal Mass Ejections (CMEs) were observed in the available coronagraph imagery in the last 24 hours.

太陽風

Over the past 24 hours, the solar wind parameters (ACE and DSCOVR) continued to reflect the ongoing influence of the high-speed stream associated with the recurrent, negative polarity, equatorial, coronal hole (SIDC Coronal Hole 147). Speed values ranged between 560 km/s and 720 km/s. The interplanetary magnetic field values were between 3 nT and 5 nT. The Bz component varied between -5 nT and 5 nT. The interplanetary magnetic field angle was mostly in the negative sector. Enhanced solar wind conditions may persist over the next 24 hours due to the continued influence of the high- speed stream.

地磁

Geomagnetic conditions globally and locally were mostly at quiet to active levels (NOAA Kp 2 to 4+, K BEL 2 to 4). Quiet to active conditions are expected over the next 24 hours due to the continued influence of the high-speed stream from the negative polarity coronal hole (SIDC Coronal Hole 147).

質子通量水平

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

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux measured by GOES 18 and GOES 19 was mostly above the 1000 pfu threshold in the last 24 hours, with short intervals in which it fell below the 1000 pfu threshold. The greater than 2 MeV electron flux is expected to remain around the 1000 pfu threshold levels in the next 24 hours. The 24-hour electron fluence is presently at moderate levels and is expected to remain so over the next 24 hours.
