Hi all,
I have spent some time putting together an animation of TV Libra.
TV Libra is a rr Lyrae type variable star with a period of about 6hours 28mins.
This means that it should be observable for 1 full cycle on any one night around May/June. It varies in magnitude from around 11.2 to 12.5.
Very interesting star, but with four seasons in one day or so, I'd hate to live there
The animations consist of 8 frames but 5 images :: 1,2,3,4,5,4,3,2 repeating to give a rise and fall instead of a 'sawtooth'. The small field animation is running at 0.2sec/frame whereas the main one is at 0.1sec/frame.
If anyone is interested in visually obseving this interesting star, you can use the image to locate it, and it is at RA 15:18:22, Dec -08:27:43
There is a wider field version at:

Edit: there is a problem with my website: the file was there but now gone.
Edit: the link should now work.
enjoy,
Doug
