Picture of the sun taken with Coronado PST40 and zoom 24mm - afocal. Editing done with CS4 and comparison with SDO 304.

Almost perfect! Airplane in H𝛂

Temperature this morning was about -8.8°C and the sky is clear with a few clouds high in the sky. So time to make some pictures using my Coronado PST. Unfurtunately no sunflames could be observed but I could take a picture of the sun with an airplane in H𝛂. Almost perfect :)

Reverse colors of double rainbow - Alexander's band - Supernumerary band


Using CS4 to highlight the colors and to enhance the contrast shows the revers order of the colors of the second rainbow. It also shows much better the darkness between the two rainbows, which is called Alexanders dark band. And finally the picture shows also the green band underneath the violet color of the first rainbow which is called a supernumerary band.

Wow a Supernumerary Double Rainbow



Clouds, rain and sun ... the perfect ingredients for a perfect rainbow. Above Aarschot I took below pictures which not only show a perfect double rainbow but a supernumerary double rainbow.
According literature a supernumerary rainbow is defined when below the first rainbow more colors are seen beyond the normal colors. As seen on the pictures a "white" band is seen below the violet color which when enlarged consist of faint colors of green and violet. So we see from the outside to the inside red, orange, yellow, green, blue, indigo, violet and then green and violet.



As I was not sure and did ask for a second opinion to Frank Deboosere, our national weatherman and amateur astronomer. And he confirmed the supernumerary band aswell.

When searching for a picture I found some old pictures of the solar eclipse of August 11, 1999 which I observed near Virton, Belgium. Unfortunately clouds made it difficult to see the entire spectacle.
