A record EIGHTH supernova in this nearby galaxy consolidating its record as the most prolific producer of supernovae.
SN 2004dj in NGC2403 (Camelopardalis)
NGC 2403: Magnitude 8.9 - Size 23.4' x 11.8'
SN 2004dj: Magn. 12.0 CR - Type IIP
2004.09.19 20:12 UT (Denmark) - C8 @ f/6.3 - SXV-H9 - 3 x 60 sec
The SN is still very bright 50 days after discovery. I only got 3 minutes on this one before clouds rolled in.
SN 2004dj in NGC2403 (Camelopardalis)
NGC 2403: Magnitude 8.9 - Size 23.4' x 11.8'
SN 2004dj: Magn. 11.6 CR - Type IIP
2004/08/02.931 - C8 @ f/6.3 - SXV-H9 - 40 x 60 sec
The BRIGHTEST supernova since 1993, here two days after discovery.
This is the first supernova that I have observed visually.
Despite the apparent bright magnitude it was a tough object to spot
in the C8 due to poor conditions.
Astrometry was performed on this image by H. E. Bond (STScI) and reported in
IAU Circular 8385
In 2003 I made this image of NGC 2403. It shows a faint star-like object at the position of the supernova. This is likely a dense cluster of hot blue stars (one of which then blew up).
SN 2004bg in UGC 6363 (Leo)
UGC 6363: Magnitude 15.0 (B) - Size 54" x 13" - Sc

2004/04/14.872 (in Denmark) - C8 @ f/6.3 - SXV-H9 - 31 x 30 sec - bin 1x1
A case of a supernova as bright as its host galaxy.
SN 2004A in NGC 6207 (Hercules)
NGC 6207: Magnitude 11.6 - Size 3.0' x 1.2' - Sc
SN 2004A: Magn. 15.0 CR - Type II
2004/04/10.955 (in Denmark) - C8 @ f/6.3 - SXV-H9 - 7 x 60 sec
This was the first supernova of the year and is still bright four months after discovery. NGC 6207 is located next to the famous globular M13.
SN 2004bd in NGC 3786 (Ursa Major)
NGC 3786: Magnitude 12.3 - Size 2.1' x 1.1' - SBap
SN 2004bd: Magn. approx. 15.1 - Type Ia
2004/04/10.872 (in Denmark) - C8 @ f/6.3 - SXV-H9 - 12 x 60 sec - scaled to 200% size
Not easy to make reliable photometry on this one. Best estimate is 15.1 CR
SN 2004aw in NGC 3997 (Leo)
NGC 3997: Magnitude 13.4 - Size 1.6' x 0.7' - Class SBb P
SN 2004aw: Magn. 16.3 CR - Type Ia
2004/03/26.015 - C8 @ f/6.3 - SXV-H9 - 10 x 60 sec
SN 2003hl and 2003iq in NGC 772 (Aries)
NGC 772: Magnitude 10.3 - Size 10.5' x 4.3' - Class Sb
SN 2003hl: Magn. 17.0 CR - Type II - 24" east and 13" south of center

2003/10/16.931 - C8 @ f/6.3 - SXV-H9 - 30 x 60 sec
A rare case of TWO supernovae in one galaxy at the same time. 2003hl is almost 2 months after discovery and now quite dim. 2003 iq was discovered just one week before this image. An extra bonus was minor planet 6223 Dahl making a trail to the upper right of the galaxy
SN 2003hg in NGC 7771 (Pegasus)
NGC 7771: Magnitude 12.3 - Size 2.4' x 1.1' - Class SBa
SN 2003hg: Magn. 17.3 CR - Type II ? - 11.5" W and 3.9 " S of center
2003/08/25.910 (DK) - C8 at f/6.3 - MX516 - 12 min
The supernova is barely detectable in this image. At least the SN was a good excuse to image this beautiful group of galaxies
SN 2003gt in NGC 6930 (Delphinus)
NGC 6930: Magnitude 12.8 - Size 1.2' x 0.5' - Class SBab
SN 2003gt: Magn. 15.1 CR - Type Ia - 13" E and 15" S of center
2003/08/25.972 (DK) - C8 at f/6.3 - MX516 - 15 min
M74 (NGC 628) with SN 2003gd in Pisces
Mag 9,4 - surf. br. 14.2 - size 10.0' x 9.4' - class Sc
26 Oct 2003 - C8 @ f/6.3 - SXV-H9 - 46 min - bin 2x2
Classical grand design spiral galaxy. It has produced two supernovae within the last couple of years, SN2002ap and SN2003gd. The latter is still faintly visible in this image.
SN 2002bo in NGC 3190 (Leo)
NGC 3190: Mag. 11,1 - Size 4,0' x 1,5' - Class Sa
SN 2002bo: Type Ia
03 Apr 2002 - C8 at F/6,3 - MX516 - 13 min
A bright supernova, SN 2002bo, is visible superimposed on the dust lane of NGC3190 (the middle galaxy). This image shows a very interesting triplet of galaxies in Leo (that constellation seems to be full of triplets!). To the left is the elliptical galaxy NGC3193 and to the right a distorted spiral galaxy, NGC3187. The supernova reached a maximum brightness of 13.7 on April 2.
In May 2002 another supernova, 2002cv, was discovered in the same galaxy. The discovery was made with the infrared telescope of the Campo Imperatore observatory in Italy. The supernova was only visible in infrared light as it was heavily obscured by the dust disc of the galaxy. It is very rare to have TWO supernovae in the same galaxy at the same time! In 2001 I made an interesting visit to this observatory during a holiday to Italy
M74 with SN 2002ap in Pisces
M74: Magnitude 9,4 - Size 12' x 12'
SN 2002ap: Type Ib/c-pec (hypernova) - mag. 12.7 CR
2002/02/02.826UT - C8 at f/6.3 - MX516 - 14 minutes
Rare HYPERNOVA in M74. The image was recorded at low altitude in bad conditions with high winds and very poor seeing. The supernova reached a maximum brightness of mag 12.3 on 12 Feb 2002.
SN 2001dp in NGC 3953 (Ursa Major)
NGC3953: Magnitude 10,1 - Size 6,9' x 3,6'
SN 2001dp: Type Ia - mag 14.9 CR
25 Aug 2001 - C8 f/6.3 - MX516 - 6,5 min (13 x 30 sec)
My first supernova shot. The galaxy was imaged under poor circumstances low over the bright sky of The Hague. It is a type Ia supernova and was discovered on August 12. It reached a maximum brightness of mag. 14.4 on 14 Aug 2001. Better image of NGC 3953 (but without supernova)
