ARCHING PROM Alan C Tough Image taken: Oct. 18, 2008 Location: Elgin, Moray, Scotland Details: I was glad I had a look through my Coronado PST earlier today (Oct 18). This arching prom was quite faint but still spectacular. The image is a stack of 10 x 1/20th Sec exposures taken with a Canon PowerShot S45. I really must buy a webcam! ©2013, SpaceWeather.com -- This site is penned daily by Dr. Tony Phillips.
