List of supernovae sorted by Magnitude for 2003
This list of objects for the year 2003.
Coordinates are in J2000.0 format, the date is the
Discover date is actually the "Earliest Observation" date. The the "Last Mag" is the last
observed magnitude. * = 30 days old, ** = 60 days old or older.
Max Mag is the maximum observed magnitude.
Last obs is the date the object was last observed (current year assumed).
Max Date is the date of maximum observation.
The "z", or red shift, is taken from the spectra whenever possible.
For more information on any object, please click on the
