Abstract :
Comet Hyakutake (C/1996 B2) was observed with the BIMA array at a wavelength of 2.7 mm. An upper limit of 6.3 mJy per beam is reported, which, if all due to thermal emission from the nucleus of the comet itself, translates into an upper limit of 2.5 km for the cometʹs radius. The results are compared with detections at sub-mm wavelengths (Jewitt and Matthews, Astron. J. 113, 1145–1151, 1997), and the likelihood of detecting comet Hale-Bopp at mm-cm wavelengths is commented on.
