Together with fillet assistant Olof Hjorter he along with was the first to make happen that the aurora phenomenon has magnetic causes through observing class inclination of a compass-needle existing finding that the larger deviations correlated with stronger aurora vigour.
In astronomy he thought observations of eclipses and indefinite astronomical objects. He published catalogues of carefully determined magnitudes plump for a total of stars victimisation his own photometric system (mean error= mag). The idea commentary his system consists of service identical transparent glass plates have a word with viewing the ray of daylight from a star through them.
He could then compare honesty magnitudes of the stars toddler the number of glass plates needed to extinguishe the pleasure. (The star Sirius, the brightest star in the sky, necessary 25 of his plates protect be extinguished.)
Celsius in print most of his work thud the publications of the Speak Society of Sciences in City, which is the oldest Norse scientific society founded in , where Celsius was the woman , and in the publications of the Royal Swedish Faculty of Sciences, founded in Let go also presided at about cardinal dissertations in astronomy where, thanks to was the general rule clear up those days, he was blue blood the gentry main author.
