Peter comments:
The continued bad weather here culminated in flash flooding on
20th July which left us with two rooms under water, but fortunately the
observatory stayed dry. Since then the weather has noticably improved with a
run of good clear nights in the last week of the month.
During the month three NEOs were recovered at their second
apparition - 2001 RV17 at the beginning of the month with 2005 XW77 and 2003
CG11 towards the end, both of those two in collaboration with Luca Buzzi at the
Schiaparelli Observatory in Italy.
A couple of moderately fast movers were followed over several
nights - 2007 DT103 which was detected at the end of the month by RADAR from
Goldstone and found to be a binary, and 2007 MB4 that passed at about 8 Lunar
Distances on July 5th.

**Video captured using Matrox Meteor II
capture card and Sirko Molau's
'GRABSEQ' s/w. Individual separated interlaced fields were
captured and
studied visually using 'AVI2BMP' 0.49. STVASTRO time corrected for
difference between exposure and readout time
(STVASTRO time = start of
field read-out = end of field exposure).

ADDITIONAL COMMENTS
(Report submitted to Gilles Regheere and
PLANOCCULT.)
Site just north of predicted N limit.
This was my first recording using the Watec
120N, but disappointing. The
camera seems much less sensitive than the
Watec 902. Because of the
short maximum duration (1.2 sec) I used it
with the Frame Integration set
to 'OFF' i.e. normal video rate. Unfortunately this brought the star
within the strong scintillation zone and it
was not possible to
distinguish a true short occultation. (Atmospheric extinction would have
increased the magnitude to ~10.7) The video recording will be retained
in case of other reports.
