The present observatory in Bonn is in

Latitude50° 43' 45"N.
Longitude0h 28m 23sE. from Greenwich.

At the date of the first eclipse Bering was on his way across the southern end of Kamchatka from Bolsheretsk to Lower Kamchatka. This would make his position somewhere near latitude 55° N. and longitude 160° or 10h 40m E. from Greenwich.

He was therefore 10h 12m east of Bonn for which we have the elements of this eclipse as computed by Manfred. With this data together with the latitude and sun's declination we have the following data for the eclipse in the region where Bering was.

Beginning of eclipse 4h 44m
Middle of eclipse6 12
End of eclipse7 41
Sun sets5 07

This means that the sun set, bearing about W. by S. ½ S., and the moon rose in partial eclipse, bearing about E. by N. ½ N., at 5h 07m after apparent noon or 23 minutes after the eclipse had begun. The eclipse lasted for 2h 34m after sunset, or until 7h 41m in the evening, thus rendering observation of the last contact plainly visible.

At the date of the second eclipse of 1728, August 19, Bering was at sea somewhere in the vicinity of the strait which bears his name. Assuming his position to have been latitude 65° N. and longitude 188° or 12h 32m E. from Greenwich, equal to 12h 04m E. from Bonn, and as before taking the data from Manfred's ephemeris we have as follows:

Beginning of eclipse 16h 11m
Middle of eclipse17 39
End of eclipse19 07
Sun rises16 04

It thus appears that the first contact of this partial eclipse of the northern limb of the moon may have been just barely visible to Bering. The moon bearing about SW. by W. was entering the earth's shadow about five minutes before the sun's rising and its own setting. If much importance attaches to determining the possibility to Bering of observing this eclipse then a more precise calculation is needful.
