[evlatests] Fwd: missing panel pics

[George Moellenbrock]

Here's some pics I sent to Bryan documenting the missing panel, and the 
weather that caused it.

Not quite clear it is at one of the 'cardinal' points on the edge.

And it can't explain both of your bad edge panels in the holography, of 
course!

Hi Bryan-

I attach some pics of the missing panel.

missing_panel2.jpg is an early close-up (when I noticed the missing 
panel; someone else had zoomed the camera)
missing_panel3.jpg shows the panel lying near the center of the dish to 
the left of the feed housing.
missing_panel5.jpg shows the panel has slid to the edge of the dish; at 
this point, Vivek and I called the operator to have the antenna stowed 
and the panel retrieved

BeforeAfter.gif toggles between UTC=150859 and 150910, which shows when 
it actually happened: ~9:09am MDT. (Enlarged from web cam photos I was 
capturing at a wide angle to observe the move into D-array--alas 
frustrated by the wind.)

WindPlot.png is the weather station wind plot which shows that the wind 
reached it peak sustained level (~40mph, gusts to 50mph) at the same 
time.  Apparently, the whole array got a panel mount integrity test for 
~2 hours, at least for the WSW facing edges.....

NextDay.jpg shows the antenna observing with the absent panel.

Chris and Ephraim have photos from the site guys from inside the dish, 
showing some impact damage to another panel, and a view out through the gap.

-George
