The Moon has been observed using the VATLY radio telescope at frequencies of 1420.4and 1417.6 MHz in order to study the behaviour of the instrument in a domain of ux densityclose to the limit of its sensitivity. Drift scans have revealed a Moon ux density of 0:83 0:16kJy corresponding to a Moon black body temperature of 207 40 K. From these results, a limitsensitivity of 300 Jy has been inferred in agreement with earlier coarser estimates.
