Overview
- The Harvest Moon supermoon is timed for Oct. 7 at 03:48 UTC, described by outlets as 2025’s first and brightest and expected to look up to about 14% larger and 30% brighter near perigee.
- International Observe the Moon Night takes place Oct. 4 with free public sessions at venues such as the La Plata and Galileo Galilei planetariums and with NASA hosting global online activities.
- NASA’s outreach tips include using polarized sunglasses and a simple DIY viewer made by drilling a ~1.5 mm hole in a plastic bottle cap, a method shared by astronomer John Goss to tame glare and sharpen detail.
- The early-October Draconids will be difficult to see under the bright Moon, while the Orionids are expected to peak around Oct. 21 near a new Moon for darker, more favorable conditions.
- October’s observing calendar also features several comets, planetary meetups, and a large-scale Luke Jerram Moon sculpture touring public sites across Querétaro with free cultural programming.
