Mario's terrific 9/25 Rockport Public Library talk, "Human Health & Environmental Effects of LED Lighting on Our Night Skies," is available on YouTube here <https://youtu.be/efVn16_gYLI>. It's well-worth your time, especially if you're not familiar with the current state of the research into the effects of LED light at night. MPD

I missed this one. Saw an early of of Dr. Mario's in 2015. Great lecture. Question for anyone: Remember a comet that swung by in 2007??? or thereabouts that had broken into multiple pieces you could see in the scope? Hasn't appeared on any 'best comets' of the internet that I've found yet.

Found. It was *73P/Schwassmann–Wachmann*, also known as *Schwassmann–Wachmann 3* or *SW3*, 2006. Viewed it at that place in ?Essex? behind Plum Island.
