1999 Nov. 09.09 UT: m1=11.9:, Dia.=2', DC=2/... 41-cm L... Alan Hale (Cloudcroft, New Mexico) [sky conditions not especially good, with occasional cirrus passing through. I very clearly saw a diffuse object, with motion, at the expected location of component D. In a classic example of Murphy's Law, I had downloaded the incorrect DSS field and didn't realize it until I was at the telescope, and thus I didn't know precisely where to look for component A, however there is clearly nothing around that is as bright as component D. I had last looked for these objects three nights ago, unsuccessfully... the sky conditions were better then, but I had to contend with a rich star field. Has component D outburst since then?]
1999 Nov. 08.45 UT: m1=[12.5,... 20-cm L (158x)... Michael Mattiazzo (Wallaroo, South Australia) [component D May have been faintly visible at 13.0, component A was not visible ]
