Solar Eclipse... The longest eclipse that has been calculated thus far is the eclipse of July 16, 2186 (with a maximum duration of 7 minutes 29 seconds over northern Guyana) So I imagine it would be like extended period of cloud cover..
A total lunar eclipse can last up to nearly 2 hours, while a total solar eclipse lasts only up to a few minutes at any given place, due to the smaller size of the Moon's shadow. Also unlike solar eclipses, lunar eclipses are safe to view without any eye protection or special precautions, as they are dimmer than the full Moon. So there you go a lunar eclipse is dimmer then a full moon which is kind of weird but true.
So best guess no effect at all. Either too short in the case of solar and in the case of lunar not enough light...
