Scientific paper

A report of 20 stars to be occulted by Neptune and 46 stars to be occulted by Uranus during the period 1986-1990 has been provided by Mink and Klemola (1985). This paper has the objective to present J, H, and K magnitudes for most of these stars. It is pointed out that Uranus and Neptune occultation events observed in the K band give optimal signal-to-noise ratios due to the planets' strong methane absorption at 2.2 microns. Program stars and standards were observed over six nights with the aid of the 30- and 74-in telescopes at the South African Astronomical Observatory in Sutherland. The obtained results show that several bright candidates exist for both planets. The brightest are N55 for Neptune and U37, U41, and U65 for Uranus.
