A second Sun in the Sky ?

A close up of the effect with its partial rainbow & the image of the sun visible.
This was a first for me in 7 years of watching the sky in the NT seeing a Sun Dog. I almost ran off the road on my way home, as to my absolute surprise there was a “Second Sun” in the sky, just before sunset. As a Space Weather follower, I knew I had a Sun Dog. Something I have never seen in our tropical skies.
I raced for the camera and these images are the results. It even brightened before my eyes at one stage. It is amazing that tiny hexagonal ice crystals high in the upper atmosphere can align and have such a dramatic effect. These optical effects occur in a 22deg arc around the sun and can form above, below and to the sides of the sun. The closest I have seen to this is a sunbow, about 5 years ago. I will be keeping my eyes peeled for more of these & my guess is now that I am looking I will see more .

The Deep Lunar Eclipse – June 2011
There are times when the planets align perfectly and on Thursday morning
the 16th June 2011 the earth and the moon did just that,
for the deepest lunar eclipse in over 10 years.
shadow or Umbra, as it is known. Sitting beneath the overhanging
branches of a mature Mahogany tree as it framed the moon in the cool
morning air of Nhulunbuy was magical. Add the mellow sounds of Pink
Floyd, “Wish You Were Here”and the scene becomes surreal. As the eclipse
progressed and the black “bite” out of the moon grew larger the Pink Floyd
music could not have been better better choreographed had I tried.
It did not seem long before the entire moon was in the deep shadow
and glowing an eerie Coppery red. With the sky darkening sporadic
meteors shot across the western sky as if to herald the deepest part
of the eclipse. At the height of the moons eclipse, the centre of the moon
Sounds like a great excuse for a Lunar Eclipse moon party !
