Aktywne obszary słoneczne i rozbłyski

Solar activity was moderate over the last 24 hours. The largest flare of the period was an M1.8 flare from Catania sunspot group 27 (NOAA AR 3695) with peak time 11:21 UTC. Further M-class flares, an M1.4 and M1.3, with peak times 06:45 UTC and 01:06 UTC on May 29, respectively were recorded from Catania sunspot group 28 (NOAA AR 3697). The other complex region on the disk, Catania sunspot group 22 (NOAA AR 3691), was stable and produced C-class flaring. The rest of the regions were quiet and either stable or in decay. The solar flaring activity is expected to be moderate over the next 24 hours with C-class flares expected, M-class flares likely and a low probability for further X-class flares.

Koronalny wyrzut masy

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery.

Wiatr słoneczny

The solar wind conditions reflected a slow solar wind regime with speeds between 310 and 360 km/s. The interplanetary magnetic field was stable around 6nT before showing a small jump to 8nT around 05:00 UTC followed by a gradual increase to values around 10nT. The Bz component was mostly positive with a minimum value of -1 nT. Generally slow solar wind conditions are expected to continue on May 29 and 30.

Geomagnetyzm

Geomagnetic conditions were at quiet to unsettled levels (NOAA Kp 2 and Local K Bel 3). Geomagnetic conditions are expected to be mostly at quiet to unsettled levels on May 29 and 30.

Poziomy przepływu protonów

Over the past 24 hours the greater than 10 MeV GOES proton flux was below the 10pfu threshold and is expected to remain so. There is a slight chance that the proton flux may increase due to strong flaring from NOAA ARs 3697 or 3691, but this is unlikely due to their current position.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux remained below the 1000 pfu threshold as measured by GOES 16. It is expected to remain below this threshold over the next days. The 24-hour electron fluence was at nominal levels. The electron fluence is expected remain at nominal levels over the next day.
