It looks like in Colorado we have about another week
of mediocre passes until mid-May when the phase angle
should be more favorable.

I used Heavens-above.com to find the pass and path. Note
that it is listed there as Astro H.   You can also use the
other identifiers 41337 or 16012A.

I was using 7x50 binoculars and while I did see it adequately
I was fortunate that I was looking at a point where it was
at a maximum in brightness.  I had been sweeping along the
path not knowing if the time had been impacted.

I may have seen one more maximum but never saw enough clearly
to estimate a period.  Then the specular flashes interrupted
that attempt anyway and I did not time between the two that
I saw.

Perhaps the normal maximum brightness was around 5th magnitude
and the specular flashes around first magnitude.  Consider
these values rough guesses.

I first saw the satellite a short distance west of zeta Canis
Major and it went into Earth shadow around epsilon Canis Major
so I did not have a not observation period.

If is it clear in the coming evenings the path is similar every
night...getting a little higher.  I will look for the specular
flashes and attempt to time that interval.
