At the date of the first lunar eclipse of 1729, February 13, Bering was at Lower Kamchatka, in latitude 56° 03' N. and longitude 162° 15' or 10^h 49^m E. from Greenwich equal to 10^h 21^m E. from Bonn. For this place we have from Manfred:

Eclipse begins	18^h 06^m
Total immersion	19 07
Middle of eclipse	19 56
Emersion begins	20 45
Eclipse ends	21 46

Sun rises	19^h 21^m

Thus it appears that this total and almost central eclipse of the moon lasting 3^h 40^m began at Bering's station 1^h and 15^m before sunrise of February 14, the total immersion occurring 14 minutes before sunrise. It is manifest, therefore, that Bering might have observed this eclipse.

The second lunar eclipse of 1729 occurred August 8, when Bering was in or near Okhotsk and about returning to Europe. We may assume his position to have been latitude 59° 20' N. and longitude 142° 40' or 9^h 31^m E. from Greenwich, equal to 9^h 03^m E. from Bonn. This eclipse was also total and almost central, but at Bering's station was wholly invisible, beginning at 9^h 05^m A.M. and ending at 12^h 45^m P.M.
