Aktywne obszary słoneczne i rozbłyski

The solar flaring activity was at low levels over the past 24 hours. A total of 8 numbered sunspot groups were identified on the visible solar disk. All regions are relatively simply, classified either as magnetic type alpha or beta. All regions have either exhibited a decay or remained stable. SIDC Sunspot Group 860 (NOAA Active Region 4432) currently located at N12E09 has exhibited some decay and decreased the complexity of its underlying magnetic field configuration, being classified as magnetic type beta. The largest activity was a C1.8 flare (SIDC Flare 7616) peaking on May 05 at 14:12 UTC, produced by SIDC Sunspot Group 805 (NOAA Active Regions 4384, 4408, 4413, 4425). This region is now rotating behind the west limb. SIDC Sunspot Group 859 (NOAA Active Region 4429, magnetic type beta) currently located at S04W38 and SIDC Sunspot Group 856 (NOAA Active Region 4431, magnetic type beta) currently located at S16W06 have also contributed to the observed low levels of activity. The solar flaring activity is expected to be at low levels over the next 24 hours with C-class flares expected and small chances for isolated M-class flaring.

Koronalny wyrzut masy

No Earth-directed coronal mass ejections (CMEs) have been identified in the available coronagraph imagery over the past 24 hours.

Wiatr słoneczny

Over the past 24 hours the solar wind parameters (as measured by ACE at L1) have registered waning influence of the ICME arrival and a gradual return towards background slow solar wind. The magnitude of the interplanetary magnetic field (B) was elevated at the beginning of the forecasting period, registering a maximum value of 11.4 nT. It has followed a declining trend with current values around 5 nT. The north-south (Bz) component was almost entirely positive (northward), recording a minimum value of -0.3 nT. The solar wind speed was slow with values below 442 km/s. The B field phi angle was in the negative sector (directed towards the Sun) on May 05 and has switched to the positive sector (directed away from the Sun) on May 06. The solar wind parameters are expected to register pristine slow solar wind regime until late UTC on May 07 or May 08, when a high- speed stream related to the positive-polarity equatorial coronal hole (SIDC CH 158 crossing the central meridian on May 04) is expected to reach the Earth.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were quiet. Predominantly quiet geomagnetic conditions are expected for the next 24 hours with possible isolated unsettled periods. Quiet to active conditions with chances for isolated minor storms are expected in the late UTC hours of May 07 and May 08.

Poziomy przepływu protonów

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so over the 24 hours over the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as measured by GOES 18 and GOES 19 was close to, but below the 1000 pfu threshold over the past 24 hours and is expected to remain so over the next days. The 24-hour electron fluence was at nominal levels and is expected to remain so over the 24 hours.
