چکیده

We present CCD photometry of the long period asteroid 1689 Floris-Jan. On the light curve from nights 1997.02.10/11 and 1997.02.11/12 we detected coherent sinelike oscillations with a period P=4.98 ± 0.01 minutes and full range amplitude of about 0.11 mag. The observations from night 1997.03.07/08 show no light variations with this period.
