How did I miss this?

You're bucking the trend of launching closer to the equator. You took
several pictures of the sun. Can you narrate how the sun crosses the
sky up there on Feb 1?

Happy for your success.

AFAIK the "sun" in the photos is really just skylight aided by diffraction.
This was just barely above the arctic circle, so bright, indirect skylight
was present for a while around local Noon every day. But I'm an EE who
does numeric modelling as well as analog, digital and mixed system
electronics -- not a geographer nor an expert on solar lighting.

Did you see a rocket launch?

When we were over in December 2007 preparing for our launch window,
the Trice campaign launched -- two rocket salvo, two minutes apart,
I got to see the second of the two off from the pad from about a
mile away. When we launched I was in the NENS Mobile TM Supervan
watching the instrument TM strip charts and displays.

It was the same Dec 2006/Jan 2007 at Poker Flats Research Range,
30 mi N of Fairbanks, AK -- we were sharing the launch window
with another mission then. I got to see their launches, but
during ours I needed to be in TM watching the instrument
monitors and readouts.

But at ARR you are much closer to the launch site than at Poker.
So it is a more visceral observation. You can feel the first
and second stage rumbles rather than just hearing them.

I "saw" the Saturn V launch of Skylab in 1973 (just as a tourist - I
wasn't directly involved). One must put "saw" in quotes because the
experience is so much more than just seeing and hearing. TV can't
capture it. I seem to recall I was about a mile away, but that was
plenty close enough to be impressive. (I don't think they let tourists
that close any more).

One thing I recall was being able to hear/feel some of the sound as
distinct shocks, with relatively silent periods between. (Very short
silent periods - just barely detectable; perhaps it was even my
iimagination, but that's what it seemed like). Loud enough sounds can do
that, as the "speed of sound" isn't constant, and it shows up at large
amplitudes. The pressure waves will bunch together into a series of
shcks instead of smooth waves. Anyway, that was my after-the-fact
reconstructionn. In real time, there was just the experience; you had to
be there.
