I saw a rather fine sundog today, at about 11:50, here in Cranleigh. It was
to the left of the sun, by 22 degrees I should think. I couldn't see one to
the right of the sun, perhaps because there was a patch of high cloud to
the sun's left but the sky over and to the right of the sun was mostly
clear.

Yes John, there were some very good optical phenomena today. I made this
note with my 1500 ob. It is many years since I saw a good example of a 46
deg halo, albeit only partial.


Wokingham 16 January 2016
Exceptional halo display at 1150z, LH parhelion almost too
bright to look at directly, a short section of the parhelic circle,
about 30% of the 22 deg halo, white, a brilliant circumzenital
arc and about 20% of the 46 deg halo, meeting the CZ arc,
well coloured but less bright than the CZ arc. At times during
the following 45 minutes both the LH and RH parhelia came
and went, sometimes very bright, and also the CZ arc appeared
faintly. Also at different times, the LH and RH parhelia at 120 deg
were briefly to be seen. This whole display seemed to be in fall
streak cirrus at or below the Ac clouds present at around 5 km altitude.
