Use the #99997 elset from launch plus 10:47 (min:sec) until about
launch plus 1:02:34 (hr:min:sec) when another burn starts.

Use #99998 from about 1:03:14 after launch until the start of the 
PKM burn at 1:04:44 after launch.  Then use #99999.

The PKM burn occurs over Indoneasia (?) but is in darkness.  Folks
in Hawaii MIGHT have a chance to see the residue from the burn when
the payload and perigee motor exit shadow around 14:09 UT.  Payload
separation occurs at 1:08:05 after launch (13:59:05 UT if launched
at 12:51 UT).

The Second stage burn that occurs from 1:02:34 to 1:03:14 after launch
also occurs during darkness but might be visible.

Preliminary data indicated the AKM burn about 57 hours after launch 
will occur near the sun (as seen from Earth) so will not be visible.
Not great news but at least we had advance info.  Maybe another launch
will be better placed.
