On the way home from work I photographed a bright elliptical halo (
1 ). Later on as winds from a cold front pushed a lot of low level cumuliform clouds away and I was on the state route when this happened and I held my sunglasses near my car's windshield I could make out a bright arc on top of a halo and a closer look showed another halo. I pulled off on to a small road and got to watch a half decent odd radius halo. in all I got 9, 18, 20, 23, and faint 35d halos and a bright upper 23d plate arc (
2 -
3 ).

Now there's a decent catch for a day! Very nice! There seems to be some 18d plate arc action as well.
ReplyDeleteVery good Michael. You keep getting ellipses. They are seen (regularly) only by those who watch the sky relentlessly. I haven't seen for a while...
ReplyDeleteThere is poor column orientation in the pyramid display. Both the 9 and 20 halos are brighter on the sides.
Yeah you know what Marko I noticed the same thing myself that the 20d halo is brighter on the sides and 9d halo is the same. As far as the ellipse goes this is the second one for me this year and the fifth since I saw my first one in 2005 which was the first observed in the USA since 1987. As far as the odd radius display goes seeing all those rings at once was quite a joy. Next time I need to shoot more frames to do a larger stack. I am also getting better with the registax photo stacker my dad likes it too.
ReplyDeleteEllipses are difficult to see so I must agree with Marko: one must be a truly active sky watcher to be able to see them as often as you, Michael.
ReplyDeleteHigh cloud odd radius season is on! Very nice.
Very nice ! I haven't seen ellipses so far nevertheless I consider myself very active sky watcher. I guess it also depends on your residential location - open inland, coastal area, mountain region...Michael where do you live ? What was the sun's elevation at the time of taking the shots ?
ReplyDeleteVery nice, Michael! I've seen ellipses only twice since 2002, when I started this halo thing.
ReplyDeleteMarko I don't know what the elevation was I saw after I left work at 3:30 PM I live in Ohio USA
ReplyDeleteMika!
First time I heard from you I love you homepage you got nice photos. I hope for more halos soon!!!
Congratulations on this catch, Michael. It must have been a grand day!
ReplyDeleteAccording to my calculations the sun's elevation was 45.3 degree at 3:30PM.
ReplyDeleteThe sun hits its peak elevation 72.5 degree in the middle of June in Ohio. Interestingly most of the pyramidial stuff has a broad or somewhat spread out look at this elevation.
I bet the circumscribed halo looks fantastic and so is the CHA.
Yes Agnes that was a sweet catch indeed.
ReplyDeleteI know one thing Marko the sun can get quite high in Ohio USA. I can't wait to see CHA this year myself.
Nice shots, Michael! Congrats!
ReplyDeleteThanx Jakub I appreciate it.
ReplyDeleteHave you ever saw odd radius or ellipse before?
