		Argelander enthusiastically made observations until, on 4th day of September, 1827, he wrote to his observing log: "Here observations were disrupted by a terrible fire, which burned down almost all of the city, saving, thanks to God, the observatory intact."
		Argelander's most important work was a major charting, began in 1852, that produced the Bonner Durchmusterung catalog.

		Friedrich Wilhelm August Argelander’s Atlas des Nördlichen Gesternten Himmels (1863) is the companion to the catalogue known as the Bonner Durchmusterung, a sky survey undertaken by Argelander and his assistants in 1852.
		An austere monument to sytematised knowlege, Argelander’s engraved atlas renounced nearly all the conventions of the tradition to which it belongs and displays a nakedly disorganised cosmos.
		A table is spread with a sheet from the atlas, a worker is engaged in systematically erasing all the data on the map.

	AAVSO: Manual for Visual Observing of Variable Stars
		Since professional astronomers have neither the time nor the resources needed to gather data on the brightness changes of thousands of variables, amateurs have been making a real and useful contribution to science by observing variable stars and submitting their observations to the AAVSO or similar organizations.
		The importance of the contribution of the serious amateur observer was first recognized in the mid-1800’s by Friedrich Wilhelm August Argelander (1799—1875), a German astronomer, famous for his Bonner Durchmusterung (BD) star atlas and catalogue.
		In 1844 when only 30 variable stars were known, Argelander wrote in an article: “ I lay these hitherto sorely neglected variables most pressingly on the heart of all lovers of the starry heavens.

		It would be easy to overlook Argelander's star atlas; at first glance, it seems to resemble the semi-professional or popular atlases that surround it in the exhibition case.
		In fact, it is something quite new and different; it is, quite explicitly, a New Uranometria, with Bayer's same intention of identifying and positioning all the naked-eye stars, but with the benefit of two hundred additional years of stellar astronomy.
		Each Argelander chart has faint constellation figures, and interestingly, these are copies of the original figures used by Bayer, as we can see by comparing this plate with Bayer's plate of Gemini.

		In the 19th century a standard system was finally adopted under which a star of any given magnitude is 2.512 times as bright as a star of the next higher magnitude; thus, for example, a star of the second magnitude is 2.512 times as bright as a star of the third magnitude.
		The mean of the magnitudes of several hundred stars found in the Bonn Durchmusterung catalog, which was prepared by the German astronomer Friedrich Wilhelm August Argelander about 1860, was taken as the standard of the scale for calibration purposes.
		With accurate instruments, such as bolometers and radiometers, astronomers today can measure differences as small as one-hundredth of a magnitude.
