	Alnitak (Zeta Orionis)
		The left hand star in Orion's Belt, the fifth brightest in the whole of Orion, and (in terms of apparent magnitude) the brightest O star in the sky.
		Like all O stars, Alnitak is a source of X-rays that seem to come from a stellar wind that blows from its surface at nearly 2,000 km/s; the X-rays are produced when blobs of gas in the wind crash violently into one another.
		Alnitak is probably only about 6 million years old and will eventually become a red supergiant before exploding as a supernova.

	Alnitak / Zeta Orionis 3
		Alnitak is the easternmost of the three stars of Orion's Belt, with Alnilam in the center and Mintaka in the west.
		Alnitak lies in a region crowded with several dusty clouds of interstellar gas actively forming new stars, including the famous "Horsehead Nebula" to the south.
		Alnitak Aa is a blue supergiant star of spectral and luminosity type O9.7 Ibe (with "peculiar" emission lines), where O-type stars are the hottest stars in the spectral sequence excluding white dwarfs.

	Alnitak (Site not responding. Last check: 2007-09-11)
		The region around Alnitak is remarkable as well, containing several dusty clouds of interstellar gas, including the famed "Horsehead Nebula" to the south.
		Like all O stars, Alnitak is a source of X-rays that seem to come from a wind that blows from its surface at nearly 2000 kilometers per second, the X- rays produced when blobs of gas in the wind crash violently into one another.
		Alnitak is probably only about 6 million years old (as opposed to the Sun's 4.5 billion year age) and it has already begun to die, hydrogen fusion having ceased in its core.

	THE SKY c
		When Alnitak and Saiph were in vertical alignment, the angle between the 'belt' stars Alnitak and Alnilam was 46 degrees and the angle between Alnitak and Mintaka, 49.6 degrees.
		Alnitak and Saiph were in vertical alignment with the angle of the 'belt' stars closely matching the three pyramids at Giza, not on the meridian due south, but somewhere in the south eastern sky as Orion was rising.
		Alnitak, the star that corresponds to G1 in the OCT, was at 45 degrees altitude as it reached its highest point in the sky due south.

	The Horsehead Nebula Finder Kit
		Alnitak is the left most belt star of Orion.
		Another reason it is a good staring point is because right next to Alnitak is a nebula that will help you gauge the conditions of the skies and whether or not an attempt to see the Horsehead nebula is even worth your time.
		Because of its proximity to bright Alnitak, and its visibility being dependent on the sky conditions, this nebula is easy to overlook.

		Alnitak (Zeta Orionis) the most eastern star of the belt stars of Orion is a remarkable tertiary star system in its own right.

	Big and Giant Stars: Alnitak
		Alnitak or Zeta Orionis is a system of three great Blue Stars.

		Left in the row of three is Alnitak, the central is Alnilam and the right one Mintaka.

	MLO PPP notes
		Since I have always been leery of putting alnitak on the internet, vega does not advertise this link (no traffic is routed between vega's interfaces.) This is still the case, but now rigel.sdsu.edu is connected to alnitak's ethernet interface.
		The basic design was to have the "ethernet" segment at MLO be a 16 node subnet (network 130.191.225.32, netmask 255.255.255.240) so that alnitak could route traffic between it's ppp0 interface and it's le0 interface.
		This meant that alnitak had to be configured to arp for this IP for other hosts on the 130.191.225.32 network.

	eSky: Orion's Belt
		Both Alnilam and Alnitak are supergiants, and Mintaka, while not quite as massive as its companions, is still a true giant.
		In fact, the stars at either end of the Belt, Alnitak and Mintaka, are the closest together in space: Alnitak is a little over 800 light years from Earth, and Mintaka a hundred light years farther away.
		This is especially true in the direction of Alnitak, where numerous nebulous structures are found.

	The Brain Shell
		Near Alnitak in the Orion Federation an eccentric society of self modifying splices called the DNA Dancers were forced to evacuate their Kv class sun which was prone to irregular outbursts and shell expulsions.
		The Alnitak AI, who was named Herne, contacted Enremdea for advice via microwormhole, and was advised to simulate reality for the uploads without informing them until the threat status could be estimated (the so-called Matrix scenario, from Earth Mythology).
		By this time the resouces of the entire Alnitak system were dedicated to running the simulation, with Herne effectively no more than a shell surrounding the simulation of Xyloplax which was now preparing to attack Metasoft.

		The longitude notation means that Alnitak is located counter-clockwise 29 degrees, 56 minutes, and 50 seconds "into" the zodiac sign of Taurus.
		The latitude notation means Alnitak is located south of the ecliptic by the given numbers of degrees, minutes, and seconds.
		Recall that we are using Alnitak as the prime meridian marker.

	Orion's Belt Stars
		Alnilam, the center star in the belt, means "a belt of pearls".
		And Alnitak, the eastern-most star, means the girdle.
		All three are at the same distance from us and, with Rigel, Saiph, and Meissa, probably formed at about the same time some ten million years ago from the molecular clouds astronomers have found in Orion.

	Alnitak
		The name of the star derives from the Arabic Al Nitak meaning "The Belt" or "The Girdle".
		Alnitak A is a blue O9.7Ib supergiant star about 15 times the diameter of the sun, at least 11,000 times more luminous than the sun.
		There is a third component, Alnitak C, almost one minute of arc away from A. This latter star, according to Burnham is probably not physically related to the A and B stars.
