Can two lunar eclipses occur in the same month?
I had come across your page regarding solar and lunar eclipses occuring together on the same month. Could you tell me if it’s possible for two LUNAR eclipses occuring on the same month? I have heard it could occur. If it’s indeed possible, even theoretically, could you please give the year/month that this could happen or already happened? The answer to your question is no: it is impossible for two umbral lunar eclipses to occur in one month, and marginally possible for two penumbral eclipses to occur (which you would have to look hard to find). In this list of lunar eclipse dates from 1950 to 2050, I couldn’t find a single occurrence to two lunar eclipses (even penumbral ones) in one month. Here is the reasoning behind the conclusions drawn above (this gets a bit technical, so stop here if you don’t want the gory details): A lunar eclipse occurs when the Earth, Moon and Sun are aligned such that the Earth’s shadow blocks part of the full Moon. We don’t get eclipses every time a full Mo
