The Transit of Venus - June 5, 2012
An Observing Project in Canada's Northwest Territories

 

Observing at Black's Lookout
a.k.a. "Venus Rock"

     On the Project's original planning webpages there were 11 observing sites listed (plus a few more in our back pocket).  The Yellowknife primary site at the Explorer Hotel was our planned observing site due to its accessibility.  However, in the days before, and certainly on the morning of, the Transit the weather models favoured a location near Behchoko.  Black's Lookout, our informal name for the hilltop beside the cabin of Alex and Bertha Black, became our chosen observing site.  The weather cooperated nicely for most of the 6 hours and 44 minutes of the Transit, except for some cirrus clouds midway and banded clouds towards the end.  We were able to observe under good conditions ingress (C1-C2), missed the internal egress (C3) and observed the final external egress (C4).  Our decision to relocate to Black's Lookout was vindicated.
     For a discussion on the geology of this observing site, see below.
     The photographs below -- in no particular order -- attempt to capture our experience on that hilltop.  Black's Outlook will be fondly remembered as "Venus Rock", at least in the minds of the Project's participants.

     Patrick Scheible of Seattle, Washington kindly provided this description of our observing site: "A couple of the observers asked me about the composition of the outcropping we observed from. I have shown samples to my mother, the geologist...  The rock is granite. It's an coarse granite (that is, large crystals) bordering on pegmatite (a granite with crystals larger than a certain size). The pink mineral is potassium feldspar. The white that has highly reflective surfaces is plagioclase feldspar. The white mineral that does not have reflective surfaces is quartz. The dark mineral (there's only a little of it) is biotite."
     John Cliff forwarded the following information: "Slave Province: North America (Janine Sandersen 2010)
