Astronomy Photo of the Day is something I usually try to catch. Stunning photos of galaxies and stuff. Well, APOD has a video for today, May 16 which has a few useful items in it for Gloucester. (Read the paragraph under the video for the non-Gloucester explanation.)
1) At 27 seconds in the setting sun with a green flash. If you have never seen one of these check it out and then the next time you are in Lanes Cove or a decent sunset viewing spot see if you can see the green flash.
2) Clouds as waves crashing into Brace Cove. at one minute and several other places.
3) Star field spinning around the North Star. You don’t have to go to a desert to get this. Go to Halibut Point State Park where the Cape Ann granite shields you from light pollution from Boston and lay on your back. If your cheap point and shoot has the ability to shoot movies in time lapse just fire it up and point it straight up. You will be amazed at the results. A tripod and pointing it at the north star helps but not necessary. You can even capture multiple shooting stars this way.
Click. Then right click and open video in a separate window so you can make it as big as possible. Watch this movie until the sun comes out. Rumor has it the sun may return in June.
