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
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.

Supermoon on November 14th- really Super?
What's in the name? On November 14th 12h21 MET the distance moon-earth will be as close as 356509km. Why is this important? It's because this happens on almost the same moment when the moon is full (14h52 MET). It's calculated that the moon will be 14% "bigger" and about 30% "more bright". As all this happens during daytime, best observation is the morning of Nov 14th or at evenings. Will you notice the difference... not really.
The last time the moon was that close happened on Jan 26th, 1948 (356461km). On November 25th, 2034 the moon will be even closer with 356445km.
So why should you look at the moon? Only it's because you know that it was about 68 years ago the moon was that close. Super right?

Solargraph missing in action
One of my pinhole camera's are installed near the abbey of Averbode since mid June - see blog. This morning during a routine inspection I noticed the camera dissapeared. Bad luck! I still have one camera running at home which I hope will make it till december 21 :)
If you want to make your own pinhole camera capturing a solargraph - see my webpage DIY Solargraph.
