Sorry, took a break to put in another load of laundry an hit "Send"
instead of "Save."  No chance to proof read.

Picking up where I left off:

The Green Bay, Wisconsin station on the 20th did not show an air
temperature for 0 or 126 m. From 214 m to 914 m the air temperature rose
from 14.6 C to 17.6 C before starting to decline with altitude. I have
no idea whether this is a normal lapse rate.

Under the heading of, "Never let the facts interfere with a good story."

Regarding side error on my sextant:  I checked it before and after the
observations. Two images of the same star slid by each other barely
kissing.  Superimposing two Sun images showed a perceptible but very
slight fringe. The acid test, tilt the sextant 20 or more to either side
while viewing a horizon that is aligned.  I did, no noticeable bump with
a 3x scope.

Bill's "thermometer" was Bill's body, life experience, and goose bumps.

The heater was on in the car as I was wearing shorts, a T-shirt, and
lightweight summer shirt with the sleeves rolled up past the elbows.
Alex was in jeans and a (long sleeve?) shirt. The car windows were
partially open. It was approx. 45 minutes after sunset on the shore when
we left for the restaurant, and almost 10 pm when we headed for Notre
Dame. Plus, I'm older than the unique Ukrainian math whiz. My car, my
gas and mileage, and Alex wants the temperature to suit him? Suck it up
Doc ;-)

To Alex's credit, the horizon was horrible when we arrived after sunset
on the 13th, but he plugged away with Jupiter. On the 17th we had what
looked like the best horizon I have ever seen on Lake Michigan under a
Sun--from the beach or offshore. My 5 shots were consistent as I chose
the time.  Alex plugged away through twilight like an old war horse even
when the front was moving in and the horizon turned unusable IMHO.
