On Saturday evening, Sue Worden, Ed Cannon, and I (Mike McCants)
traveled to a "dark sky" site about 65 miles northwest of Austin.
Quite a few other members of the Austin Astronomical Society
also attended this star party.

This site is latitude 30.88, longitude 98.43 west.

Two Molniya flashers were accidentally discovered.  In both cases
flashes to about 2nd magnitude were noticed by someone and then
the object was tracked in my 8 inch telescope.  As we watched,
the flashes gradually decreased in magnitude over a period of
about 3 minutes.

The first object was 12133, Molniya 3-14, 81-002A:

  7234  72.0 122.2    4  41   19 24.7  20.0   7361

  6944  70.1 126.0    4  43   19 29.1  17.9   7097

I watched this object again from my driveway this evening with
7x50 binoculars.

  6254  66.0 133.4    4  43   19 38.9  12.4   6468

The period was timed this evening as 14 cycles in 155.5 seconds for
a period of 11.1 seconds.  Brightest flash was to about magnitude 2.5.

The second object was 16393, Molniya 3-27, 85-117A:

   HGT   ALT   AZI  HRS MIN     R  A    DEC  RANGE
  3931  33.6 162.9    8  15   22 56.1 -24.0   4979

  3550  24.9 162.5    8  18   23 12.1 -32.2   4930

This Molniya was timed in 10 cycles in 96.4 seconds for a period
of 9.6 seconds.

Of course Ed Cannon also independently identified these objects
from the observations.
