Re: 2011 Perseids

Sorry it's taken so long to offer this one up - we had a tough observing night for the Perseids this year (with the full moon arrgh.) Only a few images from up here in the great 'almost-white' north. Honestly - we were begging for snow given the hatch of mosquitos that we had to endure for just two ...

Re: APOD: Noctilucent Clouds Over Edmonton (2011 Jul 20)

I hope I'm wrong but I seem to detect a touch of irritation and incredulity in your reply that anyone would have been confused over the date. I apologise if I have in any way upset you about that. I did of course also say that it was "a nice video and APOD picture", which they are. :) Not...

Re: APOD: Noctilucent Clouds Over Edmonton (2011 Jul 20)

According to the description, it's supposed to be the sun setting. It looks like somebody didn't check with the picture-taker. But it still looks really neat! I wonder how come the "light-pollution" came out in that shape, and in that color? Shape can be attributed to: a) shooting the cen...

Re: APOD: Noctilucent Clouds Over Edmonton (2011 Jul 20)

I am confused as to the date when the image was taken. The "above" link in the explanation brings up a video from which the APOD seems to have been captured. The video is titled 'Noctilucent Cloud over Edmonton, Canada July 1, 2011' and other information with it states it was on Canada Da...

Re: APOD: Noctilucent Clouds Over Edmonton (2011 Jul 20)

The almost square sunset is really nice. The shape reminds me of the really big fuel storage tanks with the floating tops. Except, they're not orange. Sadly - no sunset. The bulk of 'orange' visible at the horizon in the image is the light pollution of the city of Edmonton. The image was taken faci...

Re: APOD: Noctilucent Clouds Over Edmonton (2011 Jul 20)

Hey, great! I joined the RASC (Royal Astronomical Society of Canada) in Edmonton in about 1954 or 1955 - with Earl Milton, Franklin Loehde, Ian McLennan, Art Dalton,... It was WONDERFUL, great people! Dick Henry, Professor, Johns Hopkins University, Baltimore Franklin is still very much active in t...

The image was taken approximately 3 1/2 hours after sunset. Dusk was effectively over when I began shooting the display at 11:45pm local time.

Re: APOD: Noctilucent Clouds Over Edmonton (2011 Jul 20)

The image is a good example of terribly unshielded lights as well as noctilucent clouds. If these lights were adequately shielded, their illumination would be seen only on the ground. Clearly, Edmonton needs a light ordinance. Wayne Warren/Towson University. Agreed. Hands down. No contest. Of cours...
