Pics, please, gentlemen, if you can...not only am I in LA, but the whole area's covered with smoke from these damned wildfires (cough, cough...)

Pics, please, gentlemen, if you can.. Via SpaceWeather.com comes this one: http://www.spaceweather.com/comets/holmes/...Eric-Allen1.jpg It really looks like an instantaneous, symmetrical release of volatiles which are now slowly expanding to form a visible coma. The comet's brightness might stay the same (or even increase a bit) until this coma dissipates and changes the comet's appearance from a star-like object to a fuzzy, dim blob. I can't imagine what could have triggered such an event. An impact comes to mind, but are we really expected to see such a rare event, statistically speaking? Was it a simple case of falling apart under thermal stress? Who needs Deep Impact when you've got this. ![]() -------------------- |

Via SpaceWeather.com comes this one: http://www.spaceweather.com/comets/holmes/...Eric-Allen1.jpg That picture is very good, but with the naked eye it appears orangeish yellow. When I first went out to look at it I was holding the binocular in my hands (20x80 binocs are pretty heavy and you get tired of holding them up quick). I first looked at the Pleiades to make sure the focus was good. At the time I had only a rough idea where the comet was (near Mirfak according to Phil Plait - the bad astronomer). When I found the comet I thought the focus had gone out and I tried refocusing...with no luck of course. Even though he had mentioned it was mag. 3 or so, I was surprised at how bright and round it was. I might even get my little telescope out of storage for this one... -------------------- Eric P / MizarKey
