Results are presented of photometric observations of SN1987A with the Danish 0.5-m telescope at La Silla for the period February 1987-January 1988, including color lines and magnitudes from day 1 to day 300. For the first time, flux calibrations for H-beta passbands were derived. Included are also improved flux calibrations for the uvby passbands. [less ▲]

The results are presented of photographic observations of asteroid positions made in August 1976 at La Silla, Chile. The quality of the sky characteristics made it possible to record objects with the magnitude 17. Measurements of all plates were conducted with the aid of the Ascorecord measuring machine of the Royal Belgian Observatory. The reduction method employed is based on the use of five reference stars. The equatorial planet coordinates can be easily obtained from the employed parameters with the aid of the formulas considered by Smart (1944). In the evaluation procedures use was made of the SAO catalog which had been recorded on magnetic tape by the Strasbourg Observatory. Three new asteroids were discovered. The obtained data are presented in two tables. [less ▲]

Asteroids 599 Luisa and 128 Nemesis were observed photometrically at the European Southern Observatory during the 1976 opposition. The light curve of 599 Luisa shows two well-shaped minima and maxima together with a short-time-scale feature. The synodic period of rotation found for 599 Luisa 9 hr 33 min 58 (+ or -46) sec, and the maximum amplitude of the light curve is 0.18 mag. Minor planet 128 Nemesis could only be observed during one night and appears to be a slowly rotating asteroid. [less ▲]
