SUPERNOVAE 2003aj, 2003ak, 2003al, 2003am, AND 2003an
Five additional apparent supernovae have been discovered, as
tabulated below. SNe 2003aj, 2003ak, and 2003al were reported by
H. C. Ferguson, Space Telescope Science Institute, on behalf of the
GOODS Treasury Team (+ K. S. Lee) and the Hubble Higher-z Supernova
Team (cf. IAUC 8038), from images of the Chandra Deep Field South,
each object detected by subtracting images taken on 2002 July 31-
Aug. 4, Oct. 31-Nov. 3, and Dec. 19-22 from ACS images taken on
Feb. 1-5, with each new object detected independently in each of
four separate z-band (F850LP) exposures, and their z-band
magnitudes tabulated below. SNe 2003am and 2003an were LOTOSS (cf.
IAUC 8068) discoveries, reported by D. Weisz and W. Li from
unfiltered KAIT images.
SN 2003 UT R.A. (2000.0) Decl. Mag. Offset
2003aj Feb. 3.19 3 32 44.33 -27 55 06.4 25.7 0".03 W, 0".08 S
2003ak Feb. 3.19 3 32 46.90 -27 54 49.3 25.8 0".28 E, 0".39 S
2003al Feb. 5.74 3 32 05.39 -27 44 29.2 24.5 0".03 W, 0".07 N
2003am Feb. 9.5 13 20 43.57 -22 02 53.5 17.8 2".9 W, 11".1 N
2003an Feb. 9.6 13 27 53.55 +28 30 29.2 16.9 4".2 E, 0".1 N
SN 2003al was detected also in two separate i-band (F775W)
exposures, while SNe 2003aj and 2003ak were only marginally
detected in the i band; none of the three HST objects was detected
in images taken on 2002 Sept. 20.99, Nov. 2.51, and Dec. 22.10 UT
(limiting magnitude z = 28). Additional approximate magnitude
estimates: SN 2003am in ESO 576-G40, 2002 Jan. 12.3, [19.0; 2003
Feb. 10.4, 17.7. SN 2003an in MCG +05-32-22, Jan. 18.5, [18.5;
Feb. 10.4, 17.0. SN 1997br also occurred in ESO 576-G40.
