Below are some photos I took in the days before and after the super moon to which I added a blue outline for ease of comparison.
Thurs., 17 March, about 40 hours before the full moon (evening photo):
March 18, about 34 hours before perihelion (morning photo; so the moon appears upside down)
March 18, 14 hours before perihion (look closely, this one appears larger than the previous two):
Hint: Look closely at the right side. The moon 14 hours before perigee fills the box and extends into the blue line on the right side, where the previous two images leave a few pixel gap.
Weather interfered with my next opportunity, the morning of March 19, when I could have photographed the moon perhaps 8 hours before perihelion. Weather interfered again the following night 7 hours past perigee. I was able to photograph the moon, but the conditions clearly show my image as unreliable or comparison:
We see little difference in size from 40 hours to 14 hours before perigee, suggesting that another14 hours later wouldn't have shown much increase in size, had I been able to photograph then. I can always photograph a gibbeous near and at perihelion to confirm my guess, a project I'll enjoy doing when perigee occurs in evening hours at my location.
So, the super moon most of us missed appears just as big and just as bright as the more frequent "almost super moons" we see every couple years. This October, however, full moon will appear near apogee, the moon's farthest point from Earth. Weather permitting, I'll photograph that one too. The difference in size with this one should be striking.
