I attempted an observation with strong twilight and
to my surprise it was quite easy to see this object.

Again the main characteristic visually in 7x50 binoculars
are the three quick flashes followed by being invisible
then three more quick flashes.   I cannot rule out other
flashing but this is what I am using to time the period.

Tonight I watched 36 periods (sets of flashes) and came up
with a period of 2.60 seconds as I did last night.

Here is the interesting aspect.   I saw Derek Kuhl's post
about the period being 1.3 seconds last night.  Exactly
one half of my observed period.  Then I saw his video
posted a few minutes ago and timed them as I did mine
and I got 1.3 seconds.

My technique is to click the stopwatch every two sets of
flashes.  If I miss, I go to four sets.  This yields
around 5.2 or 10.4 seconds.  2 into 5.2 seconds is 2.6 seconds
as my math over a reasonable set of flashes works out to.

What I do not understand is how I am getting 2.6 seconds
while Derek gets 1.3 seconds.  His is on video and I get the
same result that he does.   Unless there is a flaw in my
observation, timing and/or math, I do not understand how
I get double the period.

Elset epoch information for 41337 below.
