Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the last 24 hours. Only several C-class flares were observed. The larger one was a C7.5-class flare today at 12:25 UTC from the currently most complex region on the disc, NOAA Active Region AR-3340 (Beta-Delta). The other active regions were also active producing several C-class flares. We expect the activity remaining mostly at low levels with several C-class flares, and possible isolated M-class flare in the next 24 hours.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours.

Dziury koronalne

A small northern coronal hole with negative polarity crossed the solar meridian on Jun 24. It is expected to have a small impact to geomagnetic conditions around the 28 June.

Wiatr słoneczny

The solar wind conditions were affected by the passage of the coronal mass ejection glancing blow (associated to the X flare on Jun 24). The wind speed was between 482 km/s to 546 km/h. The total interplanetary magnetic field (Bt) decreased from 11.3 nT to the current values around 5 nT. The Southward component (Bz) was fluctuating between -9.5 nT and 6.0 nT. The interplanetary magnetic field phi angle was predominately negative, directed towards the Sun during the past 24 hours. The solar wind conditions is expected to start waning in the next 24 hours. Then mild enhancement is expected due to the arrival of the high-speed streams from the coronal hole (negative polarity) that crossed the solar meridian on Jun 24.

Geomagnetyzm

Geomagnetic conditions were mostly quiet (NOAA Kp<4). Active conditions were observed by the local stations in Belgium (K_BEL=4) between 18:00 UTC and 21:00 UTC on June 25. Geomagnetic activity is expected to be mostly quiet for the next 24 hours, then possible unsettled to active condition may be expected with the solar wind enhancement due to the arrival of the high-speed streams associated with the coronal hole (negative polarity) that crossed the solar meridian on Jun 24.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was at background levels over the past 24 hours and is expected to remain so for the next 24 hours.
