Сонячно-активні області та спалахи

Solar flaring activity was low over the past 24 hours, with several C-class flares recorded. The largest flare was a C7.4 flare (SIDC Flare 6599), peaking at 06:12 UTC on January 7, associated with SIDC Sunspot Group 722 (NOAA Active Region 4334; magnetic type beta-gamma), which was the main driver of the flaring activity observed. There are currently ten numbered active regions on the visible solar disk. Two new regions emerged and were numbered: one in the northwestern hemisphere (SIDC Sunspot Group 757, N26W26; magnetic type beta) and one in the southeastern hemisphere (SIDC Sunspot Group 758, S05E58; magnetic type beta). SIDC Sunspot Group 709 (NOAA Active Region 4323; magnetic type beta), SIDC Sunspot Group 744 (NOAA Active Region 4324; magnetic type beta), SIDC Sunspot Group 745 (NOAA Active Region 4325; magentic type beta) and SIDC Sunspot Group 755 (magnetic type beta) are approaching the west limb but remained quiet. SIDC Sunspot Group 754 (NOAA Active Region 4336; magnetic type beta-gamma-delta) is the most complex active region on the disk but produced only low-level C-class flares. Solar flaring activity is expected to remain low over the next 24 hours, with C-class flares likely and a chance for M-class flares.

Корональні викиди маси

A faint coronal mass ejection (SIDC CME 619) was observed in SOHO/LASCO-C2 at around 02:12 UTC on January 6, directed toward the southeast from Earth’s perspective. The CME is likely associated with a C2.1 flare, peaking at 00:21 UTC on January 6, produced by SIDC Sunspot Group 722 (NOAA Active Region 4334) and a small coronal dimming. Analysis indicates a possible glancing blow impact at Earth early on January 09. No other Earth-directed CMEs were detected in the available coronagraph imagery over the past 24 hours.

Корональні діри

A small negative polarity coronal hole (SIDC Coronal Hole 145) in the southern hemisphere has started to cross the central meridian today, on January 7.

Сонячний вітер

Over the past 24 hours, solar wind parameters reflected a slow solar wind regime. The solar wind speed decreased from around 380 km/s to 320 km/s. The interplanetary magnetic field remained below 7 nT, and its southward component reached a minimum of about -5 nT. Slow solar wind conditions are expected to prevail over the next day. On January 8-9, solar wind conditions may become slightly enhanced in case of the arrival of a high-speed stream associated with a large recurrent negative polarity coronal hole (SIDC Coronal Hole 144) and a possible ICME arrival associated with the CME that lifted off the solar surface at around 02:00 UTC on January 6 (SIDC CME 619).

Геомагнетизм

Geomagnetic conditions were quiet both globally and locally over Belgium (NOAA Kp = 1 to 2+; K-Bel = 1 to 2). Mostly quiet geomagnetic conditions are expected over the 24 hours. On January 8-9, geomagnetic conditions are expected to reach active levels, with isolated minor and moderate storm periods possible, due to the expected arrival of a high- speed stream from a large recurrent negative polarity coronal hole (SIDC Coronal Hole 144) and a possible ICME arrival associated with the CME that lifted off the solar surface at around 02:00 UTC on January 6 (SIDC CME 619).

The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at background levels over the past 24 hours and is likely to remain so over the next 24 hours.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux, as measured by the GOES-19 satellite, exceeded slightly the 1000 pfu threshold between 14:40 and 17:05 UTC on January 6 and remained below the threshold for the rest of the period. The greater than 2 MeV electron flux, as measured by the GOES-18 satellite, remained below the 1000 pfu threshold over the past 24 hours. The greater than 2 MeV electron flux is expected to remain below the 1000 pfu threshold over the next 24 hours. The electron fluence was at normal levels and is expected to be at normal levels over the next 24 hours.
