Additional NOSS 2-3 search elements

Here are additional search elements for NOSS 2-3. The first is
the same second stage elset I posted last night. The second is
for the (C) object of the NOSS triad, based upon 91076C of
NOSS 2-2. I attempted to make the elset predictive by recreating
the key positional circumstances that existed shortly after
the NOSS 2-2 launch. The inclination and mean motion correspond
to current NOSS 2-1 and NOSS 2-2 values, on the assumption that
NOSS 2-3 would be synchronized with them.

If all my assumptions prove correct, then predictions should be
very accurate - to within a few minutes in time, and a fraction
of a degree of arc. My guess is that would be too optimistic, so
it would be best to treat this as a search orbit, and not put too
much faith in the epoch and mean anomaly. In fact, it is quite
likely that the mean anomaly will be phased with NOSS 2-1 and 2-2
in a special way. I do not have time to pursue the possibilities
related to that, but perhaps there are others who would like to
take a shot at the problem.

The orbit of the rocket and payload is in morning visibility at
approximately 30 N, just starting morning visibility at 45 N,
and a few days away from morning visibility at 55 N. So there
will be plenty of opportunities to search. I have not evaluated
the southern hemisphere situation.

Weather permitting, I will make an effort to do some searching.

bye for now
