I have trouble picturing eclipses and whether the moon can be directly overhead.

  • $\begingroup$ Define "directly overhead" -- presumably you mean Elevation of 90 degrees from your point of view? $\endgroup$ – Carl Witthoft Aug 3 '18 at 14:30

    $\begingroup$ The sun is always overhead somewhere on Earth. So it must be overhead during eclipses, too. $\endgroup$ – Mark Olson Aug 3 '18 at 14:44
  • $\begingroup$ @MarkOlson well, that does not need to be the place where the moon's umbra (or even the penumbra) is. $\endgroup$ – Glorfindel Aug 4 '18 at 14:00

    $\begingroup$ @Glorfindel Fair enough, but some eclipses are central and those will be overhead somewhere. I don't think the questions was where all eclipses must be overhead somewhere, but whether any are. $\endgroup$ – Mark Olson Aug 4 '18 at 14:17
  • $\begingroup$ When I first travelled to the tropics, I was expecting to see the Sun directly overhead at some point. I hadn't thought about the Moon. I experienced this first and was surprised for a moment before thinking: well, of course, that was going to happen as well. $\endgroup$ – badjohn Aug 5 '18 at 9:06

They could be directly overhead if you live in the tropics.

The tropics are the regions near the equator, between 23 degrees North and 23 degrees south. In the tropics, the sun and the moon can pass directly overhead. If both pass overhead at the same time there will be a solar eclipse directly overhead.

The eclipse of July 11, 1991 was visible directly overhead, (to within a degree) and in totality, for observers in the Nayarit province in Mexico

    $\begingroup$ Indeed, and a good example of that, is the eclipse of July 11, 1991, it was visible directly overhead, and in totality, for observers in the Nayarit province in Mexico $\endgroup$ – FSimardGIS Aug 3 '18 at 14:13
