Subject: Partial Halo CME on 2001/10/03, backsided

  ------------------------------------------------------------------------

LASCO observed another large partial halo CME on 2001/10/03, in addition
to the one reported yesterday. A bright loop front was first observed
in C2 in the N and NW at 15:30 UT; this front spanned 200 deg over both
the E and W limbs by 17:06. Additionally a very faint extension, probably
a shock could be seen over the S pole. The bright front first appeared in
C3 at 16:16 UT with maximal coverage by 19:45.

There is no significant activity observed on-disk by EIT, but very faint
emission can be seen over the N and NW limb between 13:48 and 15:24 UT.
This is consistent with a backsided source some way from the limb; thus
this event has been determined backsided.

Best wishes,
        Gareth Lawrence.
