PRESTO FROM SIDC – RWC BELGIUM Fri Sep 21 2012, 1444 UT

Three full halo CMEs were observed last 24 hours. The SOHO/LASCO C2 observations show first appearance of the two halo CMEs on September 20, at about 05:48 and 15:12 UT, respectively. The full halo CME observed this morning appeared in the SOHO/LASCO C2 field of view at about 06:12 UT. From the currently available data it seems that all three CMEs were back side events and associated with the flares at about at E150 as seen from the Earth. The CMEs will therefore not arrive to the Earth.

# HALO CME ALERTS from the SIDC (RWC-Belgium), generated by CACTUS   #
#——————————————————————–#
  A halo or partial-halo CME was detected with the following characteristics:

            t0      | dt0| pa | da |  v  |  dv | minv| maxv|
052|2012/09/20 15:12| 04 | 111| 324| 0905| 0304| 0140| 1735

Details can be found here: http://www.sidc.oma.be/cactus/out/latestCMEs.html

      t0: onset time, earliest indication of liftoff
     dt0: duration of liftoff (hours)
      pa: principal angle, counterclockwise from North (degrees)
      da: angular width of the CME (degrees),
       v: median velocity (km/s)
      dv: variation (1 sigma) of velocity over the width of the CME
   mindv: lowest velocity detected within the CME
   maxdv: highest velocity detected within the CME

  This message is sent whenever a CME wider than 150 degrees is detected by cactus.

COMMENT: Six sunspot groups were reported by Catania today and non of
them was particularly active, with only three weak C-class flares
reported during last 24 hours. We expect more C-class flares from the
Catania suspot groups 85 (NOAA AR 1574), 87 (NOAA AR 1575), and 88 (NOAA
AR 1576), and possibly also on the M-class flares. Three halo CMEs were
observed last 24 hours. From the currently available data it seems that
all three CMEs were backsided and originated from the active region
currently situated just behind the east limb. The influence of the fast
flow which arrived yesterday morning is decreasing. The solar wind speed
is at the moment about 45o km/s and decreasing. The interplanetary
magnetic field magnitude is around 5 nT. We expect quiet to unsettled
geomagnetic conditions in the following hours, due to the remnant
influence of the fast flow.

TODAY’S ESTIMATED ISN  : 058, BASED ON 13 STATIONS.
