This December 3, 2003, will be a key date in my halo hunter life! All has started this midday when I abandoned my pasta to have a quick look to the sky outside. I saw a circumzenithal arc that I decided to record with my digital camera.
It's between 14 o'clock and 14:45 local time that the display became great! The circumzenithal arc reappear, but this time, it is along with very bright and colorful parhelion, showing nay the starting of a parhelic circle. Sticked to the circumzenithal arc, the supralateral arc is visible!
Standing at the middle of my street, facing the Sun masked by a street-lamp, I take many picutres. I'm like a fool (neighbours who saw me think I'm really crazy...)!
This digital composite presents the phenomenon in its globality. Unfortunately, the digital camera is saturated in the inner parts of the 22 degrees halo.
But the other picture taken onslide with a fisheye lens support more easily the brightness range.
An anotated version with the names of the visible structures is available here (127 ko). |
