The 2010 perihelic
opposition of Jupiter observed from Barbados ... Damian A. Peach
year 2010 was set to be a memorable time for Jupiter enthusiasts. After
years of being placed low in the sky for northern hemisphere observers,
the giant planet would finally move north of the celestial equator.
Better still, the opposition of 2010 presented observers with Jupiter
at its largest apparent angular diameter since the opposition of 1963.
This made an opportunity that was too good to be missed, so I
arranged to stay on the tropical island of Barbados in hope of
obtaining many excellent images, as had been possible there on previous
a tool for amateur supernova hunting ... Dominic Ford
This paper presents
GrepNova, a software package which assists amateur supernova hunters by
allowing new observations of galaxies to be compared against historical
library images in a highly automated fashion. As each new observation
is imported, GrepNova automatically identifies a suitable comparison
image and rotates it into a common orientation with the new image. The
pair can then be blinked on the computer’s display to allow a rapid
visual search to be made for stars in outburst. GrepNova has been in
use by Tom Boles at his observatory in Coddenham, Suffolk since 2005
August, where it has assisted in the discovery of 50 supernovae up to
Noctilucent cloud over Britain &
western Europe, 2009–2010 ... Ken Kennedy
Record amounts of
noctilucent cloud were reported in the 2009 season, but they were
significantly fewer in 2010. Weather conditions in the UK and Europe
may have been poorer in 2010 but increasing solar activity may also
have had the effect of reducing the number of nights on which NLC was
observed. This report presents observations of NLC received in 2009
& 2010 from western Europe and the British Isles.
The unusual case of ‘asteroid’ 2010 KQ:
a newly discovered artificial object orbiting the Sun... Richard Miles
Observational evidence is presented which demonstrates that object 2010
KQ is artificial in nature and is almost certainly the upper rocket
stage of a Russian Moon probe. The only possibilities identified are
the rocket stages associated with the launches of Luna-1 (1959
2), Luna-4 (1963 April 2) or Luna-23 (1974 October 28).
Planet Center has renamed the object RK252A5.
outbursts and superoutbursts in the SU UMa-type dwarf nova NN
Camelopardalis ... Jeremy Shears et al.
We report photometry
of three outbursts of NN Cam in 2007, 2008 and 2009. The 2007 event
started with a normal outburst, lasting about 4 days, which was a
precursor to a superoutburst lasting at least 13 days. Both the
precursor and the superoutburst had an amplitude of 4.9 mag above mean
quiescence. Superhumps with a maximum peak-to-peak amplitude of 0.22
mag were detected during the superoutburst.
first confirmed superoutburst of the SU UMa-type
dwarf nova SDSS J083931.35+282824.0... Jeremy Shears et al.
We report unfiltered
CCD photometry of the first confirmed superoutburst in 2010 April of
the recently discovered dwarf nova SDSS J083931.35+282824.0. From a
quiescence magnitude of ~19.8 it rose to 14.0, an outburst amplitude of
at least 5.8 magnitudes. Only the plateau phase of the outburst was
observed, during which superhumps with peak-to-peak amplitude of up to
0.28 magnitudes were present, confirming this to be an SU UMa-type
