Events of Interest August 10, 2023

Dear Friends and Acton Conservation Trust Members,

Instead of finding a monarch caterpillar on this milkweed leaf,  I found a native hickory tussock moth caterpillar.  It has hairs with barbs that can stick into one’s skin and its back contains rash-giving venom!  Do not touch!  The good news is that there are plenty more leaves if a monarch caterpillar presents itself.

The following news and events may be of interest:

Perseid Meteor Shower
When does the Perseid meteor shower peak?
The 2023 Perseid meteor shower peaks on the night of August 12 and the morning of August 13. The Perseids usually put on a good show and this year may produce 50 to 75 meteors per hour at a dark site. The 2023 Perseids peak right before a new Moon, meaning the skies will be particularly dark, which is ideal for viewing. 
Like most meteor showers, the Perseids are caused by the debris of a comet that once crossed Earth’s path. In this case, the shower is caused by debris from comet Swift-Tuttle. The comet’s 133-year orbit carries it out beyond Pluto. It last visited our inner Solar System in 1992.
