There are a number of interesting objects with low inclinations and
high eccentricity.  I observed this Centaur rocket, Comstar 3 Rk,
10976, 78 68B, in April with a flash period of 4.8 seconds.

Here is a prediction from Highfly:

Lat  -30.335 Long -153.082 (East is negative for Highfly, too.)

Yes, the flashes are about 3 magnitudes brighter than the mag prediction
given here.

Highfly version 1.10 is now available in my ftp area as hghfl110.zip.
(http://www.fc.net/~mikem/  or  ftp://ftp.fc.net/pub/users/mikem/
or  ftp ftp.fc.net, cd pub/users/mikem, binary, get hghfl110.zip)

(No, Jay, your requested enhancements are not in this version.)

Elements for eccentric objects are in eccen.zip.
