Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low, with only C-class flares recorded over the past 24 hours. The largest flare was a C3.5 flare (SIDC Flare 4582), peaking at 12:24 UTC on June 07, and was associated with an active region located just behind the northwest limb (N10W89). There are currently five numbered active regions on the visible solar disc. SIDC Sunspot Group 513 (NOAA Active Region 4105; magnetic type beta-gamma) was the main driver of the flaring activity observed over the past 24 hours, together with active regions behind the northwest limb. Other regions on the disc have simple photospheric magnetic field configurations (alpha and 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.

Koronal Kütle Atılımı

A wide coronal mass ejection (SIDC CME 516) was observed in LASCO/C2 coronagraph data starting at 01:36 UTC on June 08. The CME is directed primarily toward the northeast from Earth’s perspective and is probably associated with a small filament eruption in the northeastern quadrant of the solar disk. Preliminary analysis suggests that the CME is slow, with an estimated speed below 300 km/s, and is not expected to produce any significant impact at Earth. No other Earth-directed CMEs have been detected in the available coronagraph imagery over the past 24 hours.

Koronal delikler

A small, low-latitude, negative polarity coronal hole (SIDC Coronal Hole 118) began crossing the central meridian in the northern hemisphere today, June 08. The associated mild high-speed stream may arrive at Earth starting from June 11.

Güneş rüzgarı

Over the past 24 hours, solar wind parameters were slightly disturbed under the ongoing ICME influence. The interplanetary magnetic field reached values up to 16 nT, and the solar wind speed ranged between 420 and 450 km/s. The southward component of the interplanetary magnetic field fluctuated between -12 and 14 nT. Solar wind conditions are expected to remain slightly elevated over the next day due to the ongoing ICME and possible high-speed stream influence, with a possibility of weak enhancements on June 09 from the potential arrival of the June 06 CME (SIDC CME 515).

Jeomanyetizma

Geomagnetic conditions reached minor storm levels (NOAA Kp = 5-) between 18:00 and 21:00 UTC on June 07, due to the ongoing ICME influence associated with the CME from early June 03 (SIDC CME 514). Locally, active conditions were observed over Belgium (K-Bel = 4) between 18:00 and 00:00 UTC on June 07. Mostly quiet to unsettled conditions are expected over the next 24 hours, with a chance of isolated active or minor storm periods due to the ongoing ICME passage, possible high-speed stream (HSS) influence, and the potential ICME arrival from the June 06 CME (SIDC CME 515).

Proton akı seviyeleri

The greater than 10 MeV proton flux, as measured by GOES-18, was at nominal levels over the past 24 hours and is expected to remain at nominal levels over the next 24 hours.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux, as measured by the GOES-19 satellite, remained below the 1000 pfu alert threshold over the past 24 hours and is expected to stay mostly below this threshold over the next day. The 24-hour electron fluence was at normal to moderate levels and is expected to remain at normal levels over the next 24 hours.
