Hello all... been luking this list since January, but this is my first
question. Been exceptionally quiet recently.
I was wondering how rare Parry Arc's are in the mid lat.'s. While not
always looking up, I consider myself to be rather observant of the sky
above, and am treated to the typical (22 halo, CZ arc, sun dogs galore...)
sights not terribly infrequently, though I think what I saw yesterday was
a
first for me. I am about as certain as I can be without a photograph that
we had a parry arc in the sky. (for being a rather avid photographer I
was
very unhappy with myself for not taking my camera with me to the movies!!
Always be prepared). I am in Richmond VA, and this was observed through
1635 and 1650 yesterday the 2nd, with a solar altitude of ~22 deg. I
beleive.
The CZ arc is what first caught my as it was one of the brightest and most
colorfull that I have ever seen, about the top 33% of the 46 deg and about
the top 66% of the 22 deg halo were visible, with at times rather bright
sun
dogs, adorned with bright white outer segments of the PH arc. Aprox. 2-3
deg above the upper tangential of the 22 deg halo was another arc segment,
which when I got back from the movie and checked out Greenler, fit
perfectly
with the suncave parry arc for ~22 deg sun altitude.
The clouds were fairly typical cirrus... (cH: 4's)
any comments, particulary to how common the Parry arc is for this region.
(no joke, what was in the sky was very much like fig. 4-3 in Greenler R.,
H., & Glories... Parry's 1820 display, within the limits of what was
visible
as I described above)
All the best,
Jacob
