-------------------------------------------------------------------------
Canon EOS 60D + SamYang 1.4/85 mm, 800 ISO + ASTRORECORD astrometric
software.
What these numbers mean: http://www.satobs.org/position/IODformat.html
-------------------------------------------------------------------------


In the table above, the A object is the brighter trailing object, B the fainter
leading object. Both objects were well separated using a 2.5 second exposure and
the SamYang 1.4/85 mm lens.

The sky cleared in the afternoon, and stayed reasonably clear during the night,
although there was some thin haze, especially during the second pass, which
suffered from a field of cirrus.

Two passes were imaged. During the first pass both objects were of about similar
brightness. During the second pass, the leading object (B) was fainter and the
trailing object (A) brighter.

The A object was some 3.6 seconds early on my previous elset, the B object about
9.5 seconds early.

During both passes, the NOSS 3-3 duo also passed through the FOV. I will measure
these later.
