	Microscopium, mythology, history, characteristics and observations by telescope
		For the inhabitants of the North hemisphere he is visible during the months of June until October; however, for the inhabitants of the South hemisphere, it culminates to high altitude on the horizon and is visible during the months of autumn, winter and part of the austral spring.
		Microscopium limits the north with Capricornius, to the west with Sagittarius, the south with the constellation of Indus and to the west with Grux and Piscis Austrinus

		The telltale evidence of the proton beams was a brief but striking increase in the intensity of ultraviolet radiation at wavelengths slightly longer than the characteristic wavelength of "Lyman-alpha," the principal radiation emission of hydrogen atoms.
		This radiation was caused by protons moving downward at high speed in the atmosphere of the observed star (called AU Microscopium).
		To recognize the observed effect as corresponding to the predicted proton beams, the Hubble observers required that the phenomena must occur at the onset of a stellar flare, in the so-called impulsive phase of the flare and that it be of very short duration.

		The micron is a unit of length equal to one thousandth part of a millimetre.
		Microscopium is a small southern constellation, east of Sagittarius, formed by Lacaille in 1752.
		The mile is a unit of the imperial scale of measurement of length equivalent (as set in 1593) to 8 furlongs, 1760 yards or 1.6093 kilometres.

	Nearby Star's Dust Disc May Indicate Planets - The Daily Californian
		Just as you might see a cloud of smoke but not the fire, UC Berkeley researchers have discovered a dust disc surrounding a nearby star that may be a telltale sign for the presence of planets.
		The star, AU Microscopium, is a dim red M-dwarf only 33 light years away and 12 million years old, making it the nearest and youngest star that is a candidate for planetary formation.
		Kalas, Matthews and Liu will now focus on further studying AU Microscopium using the Hubble Space Telescope or ground-based telescopes with adaptive optics to sharpen the image, but excitement in thee astronomical community means they will have plenty of company.

		It was invented by Lacaille in 1752, and is one of several of his creations named after various instruments and tools.
		With all the accessible objects in Microscopium accounted for, I strayed across the border into neighbouring southeastern Sagittarius, another region rarely looked at, in search of more objects of interest.
		The galaxies here are no brighter than in Microscopium, so I didn't even attempt them, but larger apertures could try IC 4991, IC 4946, NGC 6890, and NGC 6902, all in the far SE corner of the constellation.

	Robert Hooke - Biography Pt.3
		He publishes three important works, Microscopium, Cometa; in which he presents his findings on the great Comet of 1677, and finally, De Potentia Restitutiva, his treatise containing his theories of elasticity and the kinetic theory of gases.
		His two works, Cometa and Microscopium were also published in the same year.
		In 1682, Hooke resigns as secretary for the Royal Society, and, realizing that much of his work is being used as the basis for the research of others such as Sir Isaac Newton, he becomes increasingly secretive about his findings.

	Unexplained Mysteries :: Revealing The Secrets Of Planetary Formation
		Paul Kalas of the University of California at Berkeley and colleagues at Berkeley and the University of Hawaii have discovered that the star AU Microscopium is surrounded by a disk of swirling dust.
		Since planets are believed to form from such disks, the discovery could shed light on planetary evolution.Direct images of proto-planetary disks - features that are thought to be produced by comets and asteroids - are very rare.
		They observed an excess of infra red in the spectrum of AU Microscopium, a tell-tale sign that the star is surrounded by a dusty disk.

		Description: To the east of Sagittarius and Corona Australis lies Microscopium in an empty area of sky.
		Features of Microscopium: The constellation resides in an empty part of the summer sky.
		The principle stars are to faint to see with the naked-eye and even offer a difficult challenge to binocular observers.

	Discovery of Flora
		During the night of my localitation and discorered was situated at south of Capricornius constellation very closed to Microscopium constellation, close to the oposition at magnitude to 9.2.
		During the oposition of 2000, Flora was situated at Capricornius constellation variing from north to south until close to Microscopium constellation.
		The observation to find it was made at differents days but to due to the low declination that it's -24º seen from Mallorca island of +40º and bad weather conditions, with a Moon close to full involved I'd seen Flora asteroid at the end of August, 2000.

	The Stellar Guide: Microscopium
		Microscopium was named by Abbé Nicolas Louis de Lacaille during his stay at the Cape of Good Hope between 1751 and 1752.
		It was named after the microscope, whose creation is attributed to Zacharius Janssen.
		It seems that several people, including Galileo Galilei, duplicated his invention at about the same time.

	AU Microscopii / AT Microscopii AB
		AU Microscopii (Mic) is now thought to be gravitionally bound to the relatively distant dim binary system of AT Mic AB (NASA's NStar Database; and Monsignori Fossi et al, 1995), located around 1.2 light-years (ly) away.
		The triple system is located around 32.4 ly from our Sun, Sol, in the northwest corner (AU Mic - 20:45:9.5-31:20:27.2 and AT Mic AB 20:41:51.2-32:26:6.8 ICRS 2000.0) of Constellation Microscopium, the Microscope -- northwest of Alpha Microscopii, southwest of Omega Capricorni, south of Dabih (Beta1,2 Capricorni), and east of Ascella (Zeta Sagittarii).
		On February 26, 2004, astronomers announced evidence for a planet around AU Mic based on the discovery of a hole in the star's circumstellar dust disk (physicsweb article; and IFA press release).

	Black Sky, Red Shift, and On Beyond Zebra
		I had my Celestron 14 ready to go before it was dark enough to see much of anything, so I looked at a few bright globular clusters in twilight, to pass time.
		It seemed strange to travel north to view the southern heavens, but the clear sky, high altitude, and absence of light pollution made it sensible to do so.
		Microscopium isn't Virgo, but with enough aperture, there are plenty of galaxies to look at anywhere clear of the Milky Way.

		Microscopium was invented after John Flamsteed mapped the sky in the latter part of the 1600s, His stars are numbered east to west within their constellations.

	The Brightest Red Dwarf by Ken Croswell
		Even among hard-core observers, few have ever seen Microscopium; its brightest star is only 5th magnitude.
		Microscopium is west-southwest of Piscis Austrinus, the well-known home of Fomalhaut, the solitary white star that lights up a relatively featureless autumn sky.
		By red-dwarf standards Lacaille 8760 is fairly luminous, having a spectral type of M0 and an absolute magnitude of 8.71, meaning it emits 1/36 as much visible light as the Sun.

		Two relatively recent additions to the celestial menagerie are the southern constellations Telescopium and Microscopium, the Telescope and the Microscope.
		The brightest stars in Telescopium and Microscopium are over one hundred times dimmer than Sirius.

		These are unpredictable, giant versions of eruptions known to occur on a smaller scale on our own sun.
		EUVE caught two such events on the red dwarf stars called AT Microscopium and AU Microscopium.
		Also, EUVE astronomers were surprised when they detected an object located outside our own Milky Way galaxy that was emitting extreme ultraviolet radiation (EUV).
