As to be expected tonight was cloudy....but with breaks.
At 2238 I spotted Object B .it was to run below the roof line so from the
location of the scope could not be imaged , but I followed it through a
couple of gaps. It was very fast.
This brief glimpse gave me a good impression of where to look for Object B
which was to follow 13 minutes later , nearly 40 degs higher in the sky..
The cloud was not kind , but , I did manage to fire off a few frames when
"A" came zipping through.
For the short time that I saw it it seemed to be at the predicted magnitude
of 1.5.
My impression is that this bird is very much like USA 129 in design , with
perhaps a greater diameter conical "barrel" and panels along each side...a
cross perhaps between Arkon and Hubble.
It is no more than about five metres in length.
>From the obs I would summise that this "is" an optical instrument.
Four raw frames have been placed at
http://satcom.website.orange.co.uk/ ( Recent Obs tag ) Range about 240
km
On the left raw frames with dark frame subtracted...on the right the same
frames without DF.
One of the solar panels is easy to see , the other slightly in shadow
This is an exceptionally hard satellite to track due to its speed ( I
thought USA 193 was difficult , but this one takes the biscuit ! ) . . . but
considering the circumstances , the results , whilst minimal , have given
us a number of pointers as to the design of this bird.
