wide.
Indeed. Halos are neat. They come in many varieties. The coolest
one I've seen was during the day. It was a cold winter day. It
was nominally clear but there was thin fog all over the sky.
Actually, it was an ice fog. There was a beautiful ring around
the sun perhaps 50 degrees in diamater. However, the cool part
was another ring that didnt center on the sun at tall. It was
paralell to the horizon and went right around the sky at the same
altitude as the sun. The two rings intersecting each other made
for very cool sight. Apparantly the horizontal ring requires
ice crystals suspended in the air to be growing in a particular
habit (crystallographers lingo) that is quite rare.
It was very cool. And a lot closer than 8.5G ly
