Supernova 2006X in M100
Supernova 2006X was discovered in M100, 12" west and 48" south of the nucleus,
in the morning of February 7, 2006 by
Shoji Suzuki and M. Migliardi
of CROSS. At the time of
discovery, it was of brightness 15.3 mag and still rising. Spectral analysis
classified this one as a supernova of type Ia, discovered well before it
reached its maximum. The maximum occurred on February 27, 2006 when its
brightness had reached mag 13.5.
This type Ia supernova may well be used to obtain an independent distance for
M100 in the future, which may be compared to the considerably good distance
determination based on Cepheid brightness using the Hubble Space Telescope.
Insight hopefully resulting from such studies might e.g. help to calibrate the
cosmological distance scale.
The image in this page was obtained by the European Southern Observatory (ESO)
using their VLT. The supernova is the brighter (lower) star of the two below
the bright nuclear region of M100.
