Scientific paper

The possible value, for contemporary stellar investigations, of the 21-century-old observations in the Almagest star catalogue is discussed. No progenitors of historic supernovae were recorded, which strongly suggests that SN 1006 was not type II and casts doubt on the high-mass interpretation of its remnant's X-ray spectrum. One noteworthy feature of the catalogue is the excessive number of Be stars among those having observations consistent with a variability hypothesis. It is concluded that the catalogue observations may not be as worthlessly unreliable as seems to have been assumed, and that the unique potential afforded by the 21 century baseline makes the catalogue worthy of serious consideration.
