# Determine full Moon position into sky from Sun position

Soon a lunar eclipse will take place soon.

I'm not sure if I will be able to see the moon during the eclipse (from 9:30 PM to 11:00 PM), because, I have some building, mountains... in my field of view.

So, I wonder:

On lunar eclipes, will the Moon position at 9:30 PM be the same than the Sun position at 9:30 AM ?

The Sun's and Moon's hour angles at those times will be similar (both about 48$^\circ$ east of the meridian), but their declinations will be opposite (Sun 19$^\circ$ north of the equator, Moon 19$^\circ$ south). The Sun in the morning will be over 30$^\circ$ higher than the Moon in the evening.
As the Moon rises and sets about 50 minutes later each day, a better predictor for the Moon's position at 21:30 on July 27 is the Moon's position at 20:40 on July 26, about 1$^\circ$ lower than the eclipse position if observing from a mid-northern latitude.
