Hello again Dave,
In a post just submitted, I used you very first numbers (imm. at 02h20m08.1s and em. at 03h05m30.0s) while here you specify different starting data :
" My position is 40d 50m 11.4 N, 73d 37m 29.6s W.
The disappearance, 13 June, 2h 20m 8.1s UT. The reappearance, 3h 8m 11.0s UT. "
No more time to-day to "rework" your example, but as just explained in the mentioned referenced post, I would use my last approximate position and start from there to "recover" your position.
Nonetheless, one thing I can quickly check is the following :
For your position at 40d 50m 11.4 N, 73d 37m 29.6s W, I am getting imm. UT = 02h20m06.1 s and em. UT = 03h08m11.7s , both results quite close from your last published data for this position (02h20m08.1s and 03h08m11.0s).
Hence, working as explained in my very last post (not published yet), I almost sure to "recover" your published position to within a couple of miles.
At least, in reply to Tony's query, the solution just submitted (not published yet) in my earlier post to-day qualifies for such an "honest" solution.
Best Regards to both of you, Dave and Tony,
Kermit
