This month hosts two very interesting celestial events. First, a partial solar eclipse on September 13, visible only in southern Africa, Madagascar and Antartica. The second, total lunar eclipse on September 28 and the closest supermoon of 2015. This full Moon is also called the Harvest Moon, in northern hemisphere, and the Blood Moon, because it ends the current lunar tetrad - series of 4 consecutive total eclipses occurring at approximately six month intervals. The totality will last 1 hour and 11 minutes.
September equinox occurs at 08:21 UTC on September 23. This day will mark the first day of fall (autumnal equinox) in the northern hemisphere and the first day of spring (vernal equinox) in the southern hemisphere.
The best time of the month to observe faint objects such as galaxies and star clusters is on September 13.
