(GCN 570) and Halpern et al. (GCN 578).  The object was\nobserved on 4 March 2000 from UTC 7 to 11:30, in standard on-off mode,\nunder good weather conditions (stable atmosphere with opacity slowly\nrising from 0.21 to 0.26), and good pointing accuracy (<2\").  The\ntotal on plus off target integration time was 7800 seconds. \nA source is clearly detected with flux density\n\n          f(250 GHz)  =  1.9 +- 0.3  mJy\n\nWe hope to continue monitoring its flux.",
