Falling ice crystals can cause arcs and halos around the Sun or Moon. There was a bright Moon and four rare lunar halos in the sky on a Saturday night in Madrid, Spain in 2012 The moon is the most visible object in the featured image. Light from the Moon is reflected through hexagonal ice crystals into a halo around the Moon. The 22-degree arcs are circumscribed by ice column ice crystals. It's rare to see a third rainbow-like Arc 46 degrees from the Moon and it's even more rare to see it above a picturesque winter landscape. It is also possible to see a part of a 46-degree circular halo. There is a famous winter skyscape that is visible between the inner and outer arcs. If you see a halo or arcs, you should invite your family, friends or neighbors to view it.

Tomorrow's picture is a comet tailscape.

The picture shows a long ion tail.
In late December, it was captured from the Canary Islands of Spain.
Please see the explanation for more detailed information.

The long tail of the comet.
Jan Hattenbach has the rights to the image.

It was too long for a telescope to see Leonard's tail. You couldn't see it with binoculars. It was too dim with your eyes. The sky was too bright. Your camera could be used from a dark location. If the comet survives today's closest encounter with the Sun, which occurs between the orbits of Mercury and Venus, it still might. The picture was created from two deep and wide-angle camera images taken from La Palma in the Canary Islands of Spain. If it survives, the nucleus will head out of our Solar System.

Tomorrow's picture is moons beyond rings.
