I am filled with dread of the approaching winter when I hear the crickets chirp.in the evening, and they started in June this year. ------------------------------ On Tue, Jul 30, 2013 10:26 AM MDT Siegfried Jachmann wrote: >Mine too but I'm thinking in terms of how many autumns do I have left. > > > >On Tue, Jul 30, 2013 at 9:15 AM, Chuck Hards <chuck.hards(a)gmail.com> wrote: > >> You hope that autumn is far-off? >> >> It's my favorite time of year. >> >> On Tue, Jul 30, 2013 at 8:26 AM, Siegfried Jachmann >> <siegfried(a)jachmann.org>wrote: >> >> > I hope so. >> > >> > >> > >> > On Tue, Jul 30, 2013 at 6:51 AM, Chuck Hards <chuck.hards(a)gmail.com> >> > wrote: >> > >> > > >> > > Orion was throwing a leg over the mountains this morning- can autumn be >> > far >> > > off? >> > >> _______________________________________________ >> Utah-Astronomy mailing list >> http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy >> >> Send messages to the list to >> Utah-Astronomy(a)mailman.xmission.com >> >> The Utah-Astronomy mailing list is not affiliated with any astronomy club. >> >> To unsubscribe go to: >> http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy >> Then enter your email address in the space provided and click on >> "Unsubscribe or edit options". >> > > > >-- >Siegfried >_______________________________________________ >Utah-Astronomy mailing list >http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy > >Send messages to the list to >Utah-Astronomy(a)mailman.xmission.com > >The Utah-Astronomy mailing list is not affiliated with any astronomy club. > >To unsubscribe go to: >http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy >Then enter your email address in the space provided and click on "Unsubscribe or edit options".

During the eclipse, Patrick made the same estimate, I seem to remember. -- Joe ------------------------------ On Tue, Jul 30, 2013 12:03 PM MDT jcarman6(a)q.com wrote: > > >The contrail shadow is an excellent example of the eye versus camera issue.

Chuck, Isn't the best night for Persieds supposed to be Monday the 12th? (I'm not an experienced enough meteor watcher to know how spread out the Persieds are.) My wife and I had intended to be in rural S. Utah on that evening, but plans are fluid at this point. John

Eye v. Camera

The contrail shadow is an excellent example of the eye versus camera issue. While an extended exposure of astronomical objects can reveal fascinating detail and color, expanding our understanding of what we see, nothing can beat the eye for moment to moment detail. The eye sees the shifting subtle detail a camera will never be able to capture. Another example is a solar eclipse. For example, the 1991 solar eclipse - with my eyes I estimated the breadth of the solar corona at seven solar radii. Three on either side of the actual sun. No picture ever published of that eclipse has captured the true extension of the corona. That image resides only in my memory.

Shadow of Contrail Near Whispering Pines Lodge Near Moab Utah
by jcarman6＠q.com 30 Jul '13

Glad to know I'm not blind - yet. Hope you have a chance to post those images, would love to see it. Sounds like it would be very difficult to get a photo of, no matter what the equipment. Also particularly glad to know it wasn't an after effect of the evening's events - which you confessed too lol.

Cosmos Rebooted

Will look for James Burke Connections. I very much enjoy programs like that. Making history come alive. While on the subject of PBS series - "Mechanical Universe." It was a series of college lectures, probably a physics class, definitely not Astronomy 101. Don't know how many episodes, perhaps 13 or so. H ave only a few on them onVHS tape (and yes I still have a system that will show it. Its a system that plays both VHS and CDs. Pat on the back for me when I bought it :))

Shadow of Contrail from Whispering Pines Oak Lodge near Moab
by jcarman6＠q.com 30 Jul '13

I don't see a shadow on the ground. The contrail was sun lit from the right side of the photo so any shadow should show to the left of the image. The left side of the contrail is dark because the sun light is coming from the right in the image. The lower part of the contrail is all dark, probably because of mountains, clouds or something blocking the sun light. Nevertheless, a great picture of the contrail.

Perseid watch?
by Chuck Hards 30 Jul '13

30 Jul '13

Is there any interest in a Persied watch from SPOC on the night of the 11th/morning of the 12th? SPOC is dark enough to catch most of the dim ones, it's close to home for many of us, and the trump card is- there's a bathroom. If I can get the 12th off work, I may go for this. Bring a scope to putter around with once-in-a-while, or maybe reserve one of the observatory scopes if available. The moon will set before the radiant rises, so conditions will be ideal if the weather cooperates. If there were several of us, we could breakfast at Denny's or someplace afterwards.

Shadow of Contrail From Whispering Oaks Lodge-Near Moab, Utah
by Dave Gary 30 Jul '13

Have any of you seen this effect before. This is a photo of the shadow of a contrail you could see from the porch of Whispering Oaks Lodge near Moab, Utah on the morning of July 27th. The shadow of the contrail was very prominent. I’ve never seen this effect before and thought it was very interesting. The shadow lasted about 20 minutes and became wider and more turbulent-looking as the contrail broke up. http://www.flickr.com/photos/78046474@N06/9396674461/
