Comet Hale-Bopp homepage at JPL.
Below is a raw R-band image of Comet Hale-Bopp that was the spectacular comet of 1997. We obtained this image at the 2.56 m Nordic Optical Telsecope, with Simo Aro at the observer's terminal, assisted by Colin Aspin.
Simo Aro studied the
time evolution of Hale-Bopp, and this particular image was obtained
on June 11/12 1996. The exposure time was 150 seconds, the zenith
distance was about 50 degrees and the detector was a thinned Loral
2Kx2K CCD.
The coloured column that emerges almost from the center of the comet
and continues upwards is an artifact of the instrument, and is not
physically connected to Hale-Bopp.
