Mezinárodní číslo slunečních skvrn :
084
Sluneční záblesky : C-class flares expected, (probability >=50%)
Geomagnetická situace : Quiet (A<20 and K<4)
Sluneční protony : Quiet
Komentář : There are five active regions visible on the solar disc, all of
them with simple alpha or beta magnetic field configuration. Solar flaring
activity was at low levels over the past 24 hours, with several C-class
flares detected. The strongest one was a C2.9 flare from NOAA AR 2307,
peaking at 16:30 UTC on 3 February. Further C class flaring is expected.
A wide CME was first seen at 10:36 UTC on 3 February by LASCO C2, with a
speed of around 400 km/s, it may arrive to the Earth on 7 February.
The greater than 10 MeV proton flux was at nominal levels in the past 24
hours and is expected to remain so in the next 24 hours. The greater than 2
MeV electron flux has been below the 1000 pfu threshold and is expected to
remain so. The 24h electron fluence was at normal levels and is expected to
remain so over the next 24 hours.
A negative polarity equatorial coronal crossed the central meridian
yesterday, its associated high speed stream will arrive to the Earth in
about 2 days.
In the last 24 hours we saw a period of relatively high magnetic field
reaching 11 nT with Bz down to -6 nT, probably corresponding to a weak
ICME, it ended at 18:00 UTC on 3 February. The solar wind speed at L1 is at
300 km/s with an interplanetary magnetic field around 6 nT, with mostly
negative polarity (oriented towards the Sun). Similar conditions can be
expected for the next 24 hours.
Geomagnetic conditions were unsettled both locally and at planetary levels
(K_Dourbes and Kp up to 3). Similar conditions expected for the next 24
hours.
