Komentář : Over the past 24 hours, the solar flaring activity has been at low
levels with nine low C-class flares observed. There are nine numbered
active regions observed on the visible side of the solar disk. Most of the
flaring activity originated from Catania group 24 (NOAA AR 3256) which has
a beta-gamma configuration of the photospheric magnetic field and is
currently the most complex active region on the visible side of the solar
disk. All other regions have an alpha or beta configuration of their
photospheric magnetic field. The solar flaring activity is expected to
remain at low levels over the next 24 hours with C-class flares expected
and a very small possibility of M-class flares.
During the last 24 hours there were no potentially Earth-directed coronal
mass ejections detected in the available coronagraph observations.
The greater than 10 MeV proton flux was at nominal levels over the past 24
hours. The greater than 2 MeV electron flux has been around the 1000 pfu
threshold since March 27 00:25UT, barely crossing the threshold and
continues to remain so. We expect it will remain around the 1000 pfu
threshold over the next 24 hours. The 24h electron fluence was at nominal
levels and is expected to remain so over the next 24 hours.
The solar wind parameters of the last 24 hours still reflect conditions of
the high speed stream that arrived on the 25th of March. The solar wind
speed increased to values of up to about 650 km/s. Starting from 16:00UT on
the 27th of March, it declined towards values of about 570km/s. The
interplanetary magnetic field strength was about 6-7 nT during the last 24
hours. We expect the solar wind speed and magnetic field to stay enhanced
as long as Earth resides in the high speed stream. From early March 30
onwards, we are expecting the arrival of another high speed stream,
associated with the negative polarity, equatorial coronal hole which
started to cross the central meridian today.
During the last 24 hours, the geomagnetic conditions were quiet with the K
and Kp values between 1-2 as reported by the local station at Dourbes and
NOAA, respectively. Geomagnetic conditions are expected to remain quiet in
the coming hours.
