List of supernovae sorted by name for 2003
This list of objects for the year 2003.
Coordinates are in J2000.0 format, the date is the
"Earliest Observation" date. The magnitude is the last
observed magnitude. * = 30 days old, ** = 60 days old or older.
Max Mag is the maximum observed magnitude.
For more information on any object, please click on the
name of the object. This will bring you directly to
the main entry for this object.
Objects named by CBAT
are at the bottom of this file, which is sorted in reverse alphabetical order.
A "missing" object is likely an object removed by TNS or discovered in the previous year.
For the year 2003, there were 754 objects reported,
348 were report via CBAT,
721 classified as supernovae,
27 classified as extragalactic novae, and
6 object were removed.
