Joe! I'm in on that hike next spring! I'd really like to photograph the "Ghost Reef"!

Sometime after the snowy season is over I'd like to lead a short hike there for our astronomical friends. It isn't astronomy but it does concern a great extinction in what seems nearly like an alien planet. -- Joe

"Cool" solar prominence at the moment
by John M. Craig 14 Oct '14

14 Oct '14

One of those amazing whispy proms visible just now. Also had some good white-light views of the sunspots. Solar viewing is hot! Can you tell I just got the requisite gear! (Still can't quite believe my wife approved the Ha scope purchase.....) Very happy with the Lunt 80mm Ha and the Thousand Oaks white light film filter--although the rim of the filter holder seems to be exactly the same ID as the OD of the lens shade; supposed to just slide over it--no go. To try it out, I had to "laboriously" fabricate an adapter out of about 16" of electrical tape. Something more complicated later (when I get time--ha! If only...). John

Hi all, don't like to brag -- well, not very much -- but here's today's Earth Science Picture of the Day (EPOD), which is by me. Best wishes, Joe http://epod.usra.edu/

These structures are seen in maps derived from spectroscopic surveys1 <http://www.nature.com/nature/journal/v513/n7516/full/nature13674.html#ref1> , 2 <http://www.nature.com/nature/journal/v513/n7516/full/nature13674.html#ref2> that reveal networks of structure that are interconnected with no clear boundaries. Extended regions with a high concentration of galaxies are called ‘superclusters’, although this term is not precise. There is, however, another way to analyse the structure. If the distance to each galaxy from Earth is directly measured, then the peculiar velocity can be derived from the subtraction of the mean cosmic expansion, the product of distance times the Hubble constant, from observed velocity. The peculiar velocity is the line-of-sight departure from the cosmic expansion and arises from gravitational perturbations; a map of peculiar velocities can be translated into a map of the distribution of matter3 <http://www.nature.com/nature/journal/v513/n7516/full/nature13674.html#ref3>. Here we report a map of structure made using a catalogue of peculiar velocities. We find locations where peculiar velocity flows diverge, as water does at watershed divides, and we trace the surface of divergent points that surrounds us. Within the volume enclosed by this surface, the motions of galaxies are inward after removal of the mean cosmic expansion and long range flows. We define a supercluster to be the volume within such a surface, and so we are defining the extent of our home supercluster, which we call Laniakea. -- ******** Beverley Getzen Retired, US Army Corps of Engineers PO Box 202 Wadesboro, NC 28170-0202 704-694-7022 *www.carolinaswritersconference.org <http://www.carolinaswritersconference.org/>* "There are times when we are powerless to prevent injustice, but there must never be a time we fail to protest."

On my calendar I have a star party at the Bangerter Harmon's tonight. But I didn't see it mentioned on the slas.us website. Anyone know? Dion

Fabulous movie. I was packed to go to SPOC and wide awake till 3 a.m. Then I just felt too tired to go. I dragged myself out of bed during totality, peeked outside and saw the clouds that are so visible in your movie.
