A great display of Undulatus Asperatus clouds over Pennsylvania yesterday. They can be tricky to photograph, but it helped that they hung around for hours.

September is the best month of the year, especially in terms of weather. The only drawback? We're losing too much daylight! www.accuweather.com/en/space-new...

This tree went to the moon!
This Sycamore is one of dozens of trees growing around the world that went to the Moon with Apollo14 while they were still seeds. It was planted in Hollidaysburg, PA to commemorate the bicentennial.

It's an off year for the #Perseid meteor shower due to the moon, but some blaze so bright that the moonlight isn't an issue.
There's also a window between nightfall and moonrise to look for evening "earthgrazers" (I counted 6 of them last night in 30 minutes!) www.accuweather.com/en/space-new...
