A total eclipse of the Moon occurred on Monday 20 July, 1739 UT (9 Jul, 1739 Old Style), with maximum eclipse at 16:09 UT. A shallow total eclipse saw the Moon in relative darkness for 42 minutes and 18 seconds. The Moon was 8% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours and 12 minutes in total.

The penumbral eclipse lasted for 5 hours and 5 minutes. The partial eclipse lasted for 3 hours and 12 minutes. The total eclipse lasted for 42 minutes and 18 seconds. Maximum eclipse was at 16:09:01 UT.

Interactive Map

This map shows the visibility of the eclipse at maximum eclipse, when it was visible within the bright area on the map. Note that the map is approximate, and if you were near the edge of the area of visibility, the moon was very close to the horizon and may not have been practically visible.

You can use the zoom controls to zoom in and out, and pan to see areas of interest. The green marker in the centre shows where the Moon will be directly overhead at maximum eclipse.

The interactive map is currently not available.
