SN 1006
SN 1006 is the name given to the Supernova which was observed on Ground in the year 1006 of the Christian era. It is mentioned in texts European, Chinese, Japanese, Egyptian and Iraqi. It seems that its first observation goes back to the April 30th this year. It is probably about the most brilliant supernova observed at historical times. Its Magnitude connects is difficult to estimate a posteriori, but the fact is that it is mentioned in the European texts than the supernova of 1054, which however presented conditions of observation definitely more favorable since the Europe. The magnitude of SN 1006 was probably very high. It sometimes was estimated at -9, that is to say the equivalent of a district of the Moon (more than 60 times that of Venus), but the theory of the supernovæ and the re-examination of the historical texts suggest that it rather was about -7,5. That undoubtedly makes of it only the star have produced shades on the surface of the Ground. The supernova remained visible more than one year, which probably makes of it a supernova of the type II.
The supernova was observed in the vicinity of the star β Lupi, in the constellation of the Loup. The remanent of the supernova was discovered in the field radio only in the Années 1960. She also much was studied in the field of the x-rays and the gamma rays, and made it possible to better include/understand some of the mechanisms of acceleration of the cosmic rays.
