hello,

programming is also one of my interests

I always had in mind for a small program showing comet positions on my night sky, if the moon doens't dirsturb too much, but also if the comet doesn't stand close to a known deepsky object.

And here it is, a Java Applet. Fully made with the free Sun Java Netbeans 6.7, a very good IDE for those who like making Java!

Here you have a screenshot:

With changing the time, you see on a small sky chart:
- some stars
- planets
- sun
- moon (phase is also mentioned)
- comet

and it will be alerted if comet is close to a known deepsky object

8) for new comets appearing on our skies, I shall adjust the applet.

this is the url for launching the applet:

Hi David
I tried the applet and it's really good! Easy to use and understand.
Thanks very much for sharing this.
Cheers
Danny

The question maybe "why?" but the answer is usually "why not?"

hi,

following comets are available now
- C/2012 S1 Ison
- C/2013 R1 Lovejoy
- 2p/Encke

I'm working on it to change it into html5, so java plugin will be no longer needed and it shall work on tablets as well.
