Updating the 16 Feb 2021 observation...after looking at the
moon with my binoculars I would estimate the "length" of the
train of Starlink satellites at about 10 arcminutes.

I observed the satellites again on the morning of 19 Feb 2021.
Because of Paul Maley's report, I knew to look for two batches
of satellites.

Heavens-Above.com provided passes for all the satellites and it
was apparent that there were two batches.

Both were relatively short passes in the east exiting shadow
and heading to the southeast (descending node pass).

On the first batch I counted 27 satellites but thin high clouds
and other factors make that number an approximate value.  This
batch had the center of the pass around azimuth 106 degrees
and an elevation of 10 degrees.   Time was 450 AM MST (UT-7)
or 1150 UT.

The second batch had the path centered around azimuth 107 degrees
and elevation 18 degrees around 1200 UT.  By this time the thin
clouds made observing more difficult and I only counted 18 objects.

Rough magnitude estimate was 5 so not the great condition observed
by Paul Maley.

Observation was using 7x50 binoculars.
