Welcome to the Solar Influences Data Analysis Center (SIDC), which is the solar physics research department of the Royal Observatory of Belgium. The SIDC includes the World Data Center for the sunspot index and the ISES Regional Warning Center Brussels for space weather forecasting.

Solar Eclipse, March 20, 2015

INFO FROM SIDC - RWC BELGIUM 2015 Mar 27 14:54:57

Only weak C-class flares were reported during last 24 hours, despite the
presence of the complex beta-gamma-delta active region (NOAA AR 2305) on
the solar disc. The strongest reported flare C1.4 (peaking at 19:21 UT) on
March 26 also originated from the Catania sunspot group 13(NOAA AR 2305)
which started to decay and it currently has beta-gamma configuration of its
photospehric magnetic field. We expect C-class flares in the coming hours.
No Earth directed CMEs were observed during last 24 hours.The Earth is
currently inside a slow solar wind with the speed of about 410 km/s, and
the interplanetary magnetic field is stable with the magnitude of about
6nT. The sudden change of the magnetic field phi angle, at about 14:30 UT
on March 26 and its stable value since then, indicates crossing of the
sector boundary. The southern polar coronal hole is strongly extended
towards solar equator, up to about S35, and this part of the coronal hole
has reached the central meridian early today. The associated fast flow
might be expected at the Earth on March 30. The geomagnetic conditions are
quiet and expected to remain so in the coming hours.
