太陽活動區和耀斑

Solar flaring activity was very low over the past 24 hours. There are currently seven numbered active regions on the visible solar disk. SIDC Sunspot Group 838 (NOAA Active Region 4409; magnetic type beta-gamma) is the largest and most magnetically complex region on the disk, but it produced only several B-class flares. SIDC Sunspot Group 835 (NOAA Active Region 4404; magnetic type alpha) and SIDC Sunspot Group 804 (NOAA Active Region 4406; magnetic type alpha) are expected to rotate over the west limb over the next day. The remaining active regions are relatively simple (magnetic type alpha or beta) and did not produce any significant flaring activity. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares

日冕物質拋射

No Earth-directed CMEs have been detected in the available coronagraph imagery over the past 24 hours.

日冕洞

A transequatorial recurrent positive polarity coronal hole (SIDC Coronal Hole 154) started to cross the central meridian today, April 07. An associated high-speed stream may affect the solar wind environment near Earth from late on April 09.

太陽風

Over the past 24 hours, solar wind parameters (ACE and DSCOVR) were gradually returning to a slow solar wind regime. The solar wind speed decreased from about 550 km/s to 450 km/s. The interplanetary magnetic field remained weak, below 5 nT. The Bz component varied between -4 nT and 5 nT. Slow solar wind conditions are expected over the next 24 hours.

地磁

Geomagnetic conditions were quiet to unsettled both globally and locally over Belgium (Kp 1 to 3 and K-Bel 1 to 3). Mostly quiet conditions are expected over the next 24 hours.

質子通量水平

The greater than 10 MeV proton flux, as measured by GOES-18, was at background levels over the past 24 hours. The greater than 10 MeV GOES proton flux is expected to remain below the 10 pfu threshold over 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 GOES-19, exceeded the 1000 pfu alert threshold over the past 24 hours, with a peak value of 10696 pfu. It is expected to remain above the alert threshold over the next 24 hours. The 24-hour electron fluence was at moderate levels over the past 24 hours and is expected to remain at these levels over the next 24 hours.
