On 4 th November died our friend,  Wieslaw Słotwinski. Wieslaw  was the vice president of Krosno branch of the Polish Association of Amateur Astronomers, one of the most active observers of occultation events in the history of Polish section. His favorite field was the observation of stars and asteroidal occultations. For several years he took first place in the number of observed phenomena in Poland. Among the students of the Public School Complex in Krolik Polski he instilled the idea of discovering asteroids as part of the International Astronomical Search Collaboration program. His team discovered four new asteroids and made many unconfirmed discoveries by the end of 2018.
