(GCN #672)\nwith the 2.56-m Nordic Optical Telescope (+ALFOSC, mosaic\nof 5 pointings) on La Palma, and the 1.54-m Danish\nTelescope (+DFOSC) at La Silla, as follows:\n\nTelescope   Date                       Filter/Exp     FWHM\n\nNOT\t    2000 May 20.17 UT (t+20h)  R: 180-360 s   1.5\"\nDK-1.54m    2000 May 20.39 UT (t+25h)  R: 4x240 s     1.7\"\nDK-1.54m    2000 May 25.37 UT (t+6d)   R: 3x300 s     3.5\"\n\nObservations were hampered by moonlight. Using the photometry \nprovided by Henden (GCN #673), we obtain limiting magnitudes \nof R~20.8 for the NOT, and R~21.0 for the DK-1.5m May 20\nimage. \n\nThe exposures have been compared internally, and with the \nDSS-II (red) exposure. No candidate counterpart was found.\"",
