Aktywne obszary słoneczne i rozbłyski

Solar flaring activity over the last 24 hours has been at moderate levels, with multiple C-class and M-class flares. The largest flare was a M5.8 flare peaking at 23:13 UTC originated from NOAA active region 3719. There are currently six sunspot groups on the disc with NOAA active region 3719 producing the two M-class flares. The solar flaring activity is expected to be at low to moderate levels over the next 24 hours, with C-class flares expected, M-class flares possible and a small chance of X-class flares.

Koronalny wyrzut masy

No Earth-directed coronal mass ejection (CME) was observed in SOHO/LASCO-C2 coronographe images over the last 24 hours.

Dziury koronalne

A large north midlatitude north coronal hole with negative polarity, which has crossed the central meridian on June 18 is on geoeffective location, now in the west side of the sun.

Wiatr słoneczny

Solar wind conditions have returned to slow wind regime in the last 24 hours. The solar wind speed decreased from around 501 km/s to 388 km/s. The interplanetary magnetic field remained below 6 nT and the Bz component varied between -3 nT and 5 nT. The solar wind conditions are expected to remain in a slow solar wind regime. Then the high-speed stream from the large north midlatitude north coronal hole with negative polarity is expected to reach Earth in the next period.

Geomagnetyzm

Geomagnetic conditions were quiet (NOAA Kp 0-2, K BEL 1-2). Later, active conditions to minor storm may be observed later in the next period, in response of the high-speed stream from the large north midlatitude north coronal hole.

Poziomy przepływu protonów

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

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux was below the threshold level in the last 24 hours and is expected to remain so over the next 24 hours. The 24h electron fluence is presently at normal levels and is expected to remain so over the next 24 hours.
