Bright Supernovae - 1999
This data comes from
IAU Circulars
and occasionally more data will be provided on
IAU's
Astronomical Headlines page.
An archive of the 1999 updates and
2000 updates to this page are available.
In the year 1999, 206 Supernovae were reported
(163 last year), a new record.
48 were found in NGC and IC galaxies (34 last year), and
67 got brighter than 18th Mag (54 last year).
The brightest was
1999em
at mag 13.1 followed very closely by
1999by at mag 13.2, and then
1999cl at mag 13.6,
not even coming close to the bright SN of
last year.
We had two SN in Messier galaxies,
1999gn in
M61 and
1999cl in
M88.
Reported Supernovae
1999bs,
1999db, 1999dc,
1999cu and
1999cv turned out
to be galactic objects, and not SN, leaving us with 199.
For a time both 1999ex and
1999ee were
visible simultaneously in
IC 5179.
11 Extra-galactic Novae were also reported.
This is a list of the SN bright supernovae discovered in 1999.

main page for the latest supernovae.
