On Saturday, September 29th the Harvest Moon will rise for Chicagoans at 18:06 CDT. That’s only 28 minutes after the time it rose on Friday, unlike the average interval of 24 hours & 50 minutes. Since a Full Moon is opposite the Sun in the sky, there is an effect this month similar to the Sun rising earlier each day during March due to increasing northerly declination. In the case of the much speedier Moon, the effect is more pronounced. The short intervals provide extra moonlight for farmers harvesting into the night.
Here’s my photo of the Harvest Moon taken from Arlington Heights, Illinois on 2012 SEP 29 at 18:37 CDT, which was right at sunset and 30 minutes after moonrise. Circling hawks are included in the scene.
