Teide Observatory Arm Rotation Animation
Arm Rotation Movie from the IAC80 Telescope
New Spiral Jet in Comet Hale-Bopp. The new Hale-Bopp animation
which we attach shows the development of what appears to be a new
and extremely bright jet in Comet Hale-Bopp (1995 O1). The comet
has been observed virtually every night in September with the 82cm
IAC-80 Telescope in Teide Observatory (Tenerife, Canary Islands,
Spain). Sequences of 300s exposures were taken in R for as long as the
comet was visible each night (horizon limit approximately 20 degrees
altitude). The latest images which show the development of the jet
were taken on September 26th, 27th , 28th and October 2nd, 3th, 4th.
They have been flat-fielded and overscan corrected and then aligned to
give a constant position for the nucleus. The images were then
processed using a standard unsharp mask and summed. All images are
looked at individually, and any bad ones (eg: poor guiding) are
excluded from the summed image. In the images North is up East is
left.
