Comet West

Hey sketchers!

This time I send you an old but interesting observation of a break-up of
nucleus in three parts. This was the bright and splended comet West (1976).
In 50x magn., I could only see a streak in the bright coma, but with power of
166x, I could see the splitting parts of 7. to 8. mag.. Info on the sketch.
I look foreward to comet ISON, but I hope it will survive the perihel!!

location: Trondheim, Norway.
I used watercolor crayons on black paper.

Best wishes and clear sky from Per-Jonny Bremseth.

Hey Artists!

In this year of bright comets and while waiting for comet ISON, I will
mainly send sketches of these objects to show what can be seen in the coma!
Comet IKEYA – ZHANG was a bright and activ comet which showed interesting
structures in the coma. I observed before it was dark (twilight) to see the jets !
This comet is the same one as Hevelius observed in the year 1660.
Info on the sketch.
I used crayons (watercolor) on black paper.
Loc.: Trondheim, Norway.

Hale-Bopp’s Inner Coma

Hei Artists!

Not many artists on ASOD make sketches of the structures in the inner coma of comets.
Very interesting things may happen in the light coma, which is difficult to show photographic.
The spirals in the comet Hale-Bopp were sharp (as a painting) visually, but at best diffuse on
photos! Therefore it is very importent to document visually and on a sketch.
By using high power on the telescope you can observe details (jets) near the nucleus, and
over a period of time other interesting phenomenon, the most dramatic : you may discover a
breaking of the nucleus!
Such structures is also best seen against a lighter sky, as with observations of Venus.
Remember: Many things can happen in the head of comet ISON later this year!!
Back in 1976 , I could observe the splitting in comet West (3 parts)!
I used watercolor crayons for the sketch.
loc. : Trondheim, Norway.

Clear sky and best wishes from Per-Jonny Bremseth!

Hey Artists!

I send you the historic comet P/ Giacobini-Zinner (period: 6.6 years) from my observation
in aug, 1985. (info on my sketch).
This comet with the thin tail is the parent body of the Draconid-meteorshower which
had a major outburst 9. oct. 1985.
On that date my friend and I observed and photographed comet Halley while a rain of
meteors crossed the sky from the radiant in Draco. (I found Halley the day before).
I was happy to have seen and observed the parent body G-Z about two months earlier!
I used watercolorcrayons on black paper.
Location: Trondheim, Norway.
Best wishes from Per-Jonny Bremseth.
