The object is also detected in red and blue band images taken at\nthe 50in telecope at the Australian National University's Mt. Stromlo\nObservatory on April 26.63 UT (1800s), April 26.81 UT (1800s) and Apr\n28.68 UT (1800s). It is located at RA 19:35:03.17, DEC -52:50:46.1\n(J2000), offset from the nucleus of the barred spiral galaxy ESO\n184-82 (in the DN 1931-529 group of galaxies; Duus & Newall, ApJS 35,\n209, 1977) and coincident with the spiral arms. The object varies by\nless than 0.2 magnitudes between April 26.63 and 28.83 and has a blue\nmagnitude of 16.2 +/- 0.5. It is therefore not clear whether the\nsource is related to GRB 980425, or whether it is, e.g., a\nsupernova. Images of the object and the SB galaxy can be found at\nhttp://www.astro.uva.nl/titus.  Comparison of the Mt. Stromlo April\n26.63 UT and Apr 28.68 UT red band images at the location of the X-ray\nsource (BeppoSAX GRB MAIL N. 98/11) shows no variation > 0.2 mag down\nto about 21 mag.\"\n\nThis work is based partly upon images obtained by the MACHO Project\nwith the 50in telecope at the Australian National University's Mt. Stromlo \nObservatory.\n\n\nThis message is citeable.",
