	Jacobus Kapteyn Telescope - Wikipedia, the free encyclopedia
		The Jacobus Kapteyn Telescope or JKT was a 1m optical telescope of the Isaac Newton Group of Telescopes on La Palma in the Canary Islands.
		Now superseded by more recent and larger telescopes it was taken out of service as a common user facility in the middle of 2003.
		It is named for the Dutch astronomer Jacobus Kapteyn.

		George Ellery Hale, whom Kapteyn met at the St. Louis Conference in 1904, invited him to become a `research associate' at the Mount Wilson Observatory in Pasadena, California.
		Kapteyn retired in 1921 at the age of 70.

	The Bruce Medalists: Jacobus C. Kapteyn
		Kapteyn then organized his Plan of Selected Areas by which astronomers worldwide would determine positions and other data for vast numbers of stars.
		Kapteyn’s model of the sidereal system was valid at high galactic latitudes but failed in the galactic plane because of the lack of knowledge of interstellar absorption.
		Kapteyn’s Star – the second fastest star known.

	Comet LINEAR Continues to Disintegrate
		The innermost coma is elongated and rapidly fading.

		The Hubble Space Telescope recorded a house-sized fragment blowing away from the core on July 5th and powerful jets of gas vaporized by solar radiation have been pushing the comet to and fro.

	Here Comes Comet Linear (Site not responding. Last check: 2007-09-21)
		LINEAR may have disappointed casual stargazers, but it is intriguing professional astronomers with unpredictable behavior including jets that are perturbing the comet's orbit and an outburst in July that may have sent a fragment hurtling away from the comet's core.
		Mark Kidger, an astronomer at the Instituto de Astrofisica de Canarias, captured this picture of comet LINEAR's coma (the cloud of gas surrounding the icy nucleus) on July 25, 2000, using the one meter Jacobus Kapteyn Telescope in the Canary Islands.
		Ground based telescopes recorded transitory flares while the Hubble Space Telescope and others captured pictures of fragments flying away from the nucleus (see left).

	ESA Science & Technology: Look for Comet Linear
		The icy intruder, which is making its first visit to the inner Solar System and has just passed within 114 million km (71 million miles) of the Sun, seems to have broken up in the last few days and may rapidly fade from view.
		Observations with the Jacobus Kapteyn Telescope on La Palma suggest that the comet is dying very quickly and may disappear completely within a few days.
		Its brightness has been hard to predict with any accuracy because it is making its first close flyby of the Sun, and more than one short period of heating is usually needed to liberate enough dust particles and water vapour to create a spectacular coma and tail.

		For the last visit in November, 2001, at least the students were able to take the direct flight with one member of staff, whilst the rest of the party travelled via Spain, with a change of airports in Tenerife.
		As the Jacobus Kapteyn telescope is scheduled to close, however, this would probably be our last trip to the telescope, and a determined effort was made to organise the trip.
