Observers: Jean Lecacheux
Location: Pic du Midi Observatory, France

First detection of a jet

For this image we used the ASTRIANE camera build with a Thomson 7863 CCD device at the Nasmyth Cassegrain focus of the 105 cm telscope of Pic du Midi Observatory. The exposure time was 20 minutes. This image is the result of substraction of two narrow pass band filters (fwhm = 10 nm) in the red part of the spectrum. Then the dust continuum is removed. The jet position agrees with the rotational period derived from february 19th observations. North is up and west is on the right. The comet was at 0.515 UA from the Earth.
