Last night I was inspired to take a photo of comet 117P after seeing some recent messages on the ASV comet list regarding it. Days earlier I had looked for available comets to photograph and missed this one.
I was surprised by the length of 117P’s tail. The comet is relatively faint (around magnitude 14 I believe) yet the tail is quite elongated. While it’s not something probably worth “writing home about” it’s also not a sure bet to get a visible tail on a magnitude 14 comet. Not from my experience anyhow.
Future images of the comet will be posted on the 117P comet page.
