ASSUMPTIONS:
(A) Launch at 02:45 UT from Koln {note: erratum - fixed from
initial posting}
(B) Landing NO LATER than 14:15 UT at Dusseldorf
(A) Mid-eclipse centerline intercept 09:43 UT
(B) True Ground Speed = 483 nm/hr
(C) No wind
(D) Totality Run Start 6 minutes before mid-eclipse (MINIMUM*)
(E) Totality Run End 3 minutes after mid-eclipse (MINIMUM)
* For pre-totality portion of run 9 min would be preferable, but
for conservatove planning purposes 6 is used below.
This is
open for discussion to trade run-start time for
contingency time.
SCENARIO #1.
a) Proceed directly from CGN to NP. View eclipse on return from NP.
b) Total pre-eclipse margin is estimated at 0.496 hr (appx 30 min).
c) Suggest margin be used for NP siteseeing if not needed for eclipse
intercept.

SCENARIO #2.
a) Procede from CGN to overfly Longyearbyen in route to NP. View
eclipse on NP return.
b) Total pre-eclipse margin is estimated at 0.473 hr (appx 28 min).
c) Suggests margin be split for Svalbard and NP siteseeing.
Below suggests near-equal split - but does not need to be
that way.
If Longyearbyen is JUST vectored overflight with no
descent/ascent,
or similar for NP, margin (5) and (9) can be realloctaed.
