I don't know if I'm the first to say it, but finding Comet Holmes last night was elementary! (Everyone groan together....)
I ducked out during the World Series at about 10 p.m. to try for the comet with binoculars and it was very easy to spot, having just cleared the house next to mine. Even with a full Moon! As soon as the Red Sox won Game 2, I set up my LX-90 in my driveway and viewed it with various eyepieces. The comet certainly is a weird one. Looks like a big planetary nebula. At one point I was able to see the pinpoint pseudo-nucleus. It was interesting to consider that a week ago, the comet was so faint, I wouldn't have been able to see it with my telescope even in the darkest rural skies.
This morning, I finally checked the orbit for Comet Holmes and was intrigued that all of the terrestrial planets are all gathered between the comet and the Sun. I thought, "Why, it's like the Jupiter Effect!" Either that, or perhaps it an alien spacecraft that's been in orbit around the Sun observing us for the past 115 years and it's finally leaving — we're just seeing the rocket exhaust.
I guess I'm just tired from being up late.
