Hi Les,
Glad to hear that you're getting a lot of sundogs. Here in the tropics
I've been seeing haloes for the past week too! Given that it is already
the rainy season here in the Philippines, it is quite nice to see that
the fronts (starting areas of large dark cloud patches) are composed
of cirrus and cirrostratus clouds that cause haloes. In some instances
like last Thursday, the sun was covered by a real dark cloud near sunset,
but to the right and upper right of it were cirrus clouds. There was a
halo in these areas and a bright sundog to the right of the sun. Quite
a nice ending to the day. Yesterday (Friday), there was a weak halo after
lunchtime, when dark rain clouds were again making an appearance.
A few weeks back, while I was in the island of Mactan in Cebu, located at
about 10 deg. North, on June 13, I saw the strongest halo I have ever
seen.
It was after lunchtime, and the sun was surrounded by some haze. The
inner
portion of the ring was quite dark, and the halo around it was very
colorful.
In fact, a lot of my officemates who were there for our conference took
pictures with instamatic cameras and they all developed quite well.
Just goes to show that if you always look up, there is something that
can get to perk you up.
Keep looking up!
