A beautiful night on the east coast of Reunion Island
http://www.lucperrot.fr/
http://www.facebook.com/lucperrotphoto
Copyright: Luc Perrot I discovered this lovely place last weekend on the east coast of Reunion Island. It was evident that I had to go back at night, despite the 30-minute walk through the forest to access the site. Unfortunately, the weather was not very favorable ... Arrived around 21h on the spot, I waited patiently hoping for a thinning ... which finally arrived around midnight. 10 minutes, no more, to take this shot. Then it was the moonrise at 0:30 that allowed me to realize this shot. Our little rock reflects the first rays light from our natural satellite.

Seeing Sunspots thanks to California Fires?
I think I saw sunspot group 1734 by accident, taking a picture during sunset at Venice Beach, California, May 3rd Friday evening, the sky was a bit misty/foggy and visibility reduced by dust and smoke particles from the nearby Camarillo fires. See attached image. I only just realized this must be a sunspot group while reviewing the pictures. Based on spaceweather.com it looks like it could be #1734

Sun in CaK light (Calcium II K) May 5, 2013

Light from singly-ionized calcium ions in the Sun's upper photosphere and chromosphere (up to 2000 km altitude). Because the blue Calcium K Line (393.3 nm) is sensitive to magnetic fields, magnetically active structures show up in high contrast against the surrounding chromosphere. Places where moderate magnetic fields exist show up bright whereas images of high magnetic fields are dark.
In this CaK image, you typically see brightness along the edges of large convection cells called supergranules and in areas called plages. Dark sunspots are also visible.
Spots on the sun are areas of high magnetic field which appear dark to their surroundings (5,800K) due to their cooler temperature of around 3000-3500K. Spots consist of a dark central region (umbra) and are surrounded by an annular region of dark and bright filaments called the penumbra. Within a developing active region (sunspot
group) tiny spots form initially without a developed penumbra and are called pores. These are usually relatively short lived or can develop a penumbra and become a fully developed spot.
The chromosphere is a place of high solar activity. In the course of a few minutes we can observe changes in the ejecta and prominences, in the path of the filaments, and as matter flows following very characteristic arches. Chromosphere is also visible in the light emitted by the ionized calcium, in the violet part of the solar spectrum in a wavelength of 393.4 nm. This light comes from calcium atoms that have lost an electron.

To view the 3D image are simple instructions:
1. Place the image in the center of the screen.
2. Position yourself at a normal distance from the monitor.
3. Now cross your eyes slowly.
4. Now make the two central circles overlap in one.
5. When you've got, focuses the central image while keeping the two overlapping images.
6. You will see that the Sun in three dimensions.

IC 4628 in Scorpius (aka Gum 56)
Greetings !!
An impressive arc shaped rim of HII structure located in Scorpius tail and known as the Prawn Nebula. The center portion of the nebula is very bright and it seems there is a faint reflection component embedding it. Bright stars are part of Open Cluster named Trumpler 24 which shines at magnitude 8.6 and spans over 60 arc minutes representing approximately 250 light years across.
More information and high resolution view in the following link

Best Regards and nice week to all

The photo depicts a black cormorant (Phalacrocorax carbo), a loner, sitting quietly on a withered branch.
The sound of birds, the sight of dead trees in the backwaters of the Wisla river--I savor the taste of spring.
Kind regards,
Kamila

Bolid across Milky Way in Formentera island
Bolid from eta aquarids meteor shower crossing the sky from left to
right, apparently above the center of the Milky Way while displaying
an impressive range of colors due to air ionization.
Photographed today at 4:30 AM local time in Formentera island.

Iridescence on Altostratus Tailing
Iridescence is caused by parallel ice crystals driven in a common direction by high speed winds aloft. The tailings have to be thin enough that ice crystals all align in the same direction.
