Aspasia’s light curve was measured almost completely. Observation of the whole light curve (9,020 h) can’t yet be done because too short dark time during the night. Weather conditions were good, even moisture was pretty high – almost 90%. This time Moon wasn’t disturbing observation. We used TYC 1181-1748-1 (C1) and TYC 1181-1651-1 (C2) as […]
We observed the light curve of the asteroid 409 Aspasia first time in Taurus Hill Observatory (A95) at 14/15 of September in 2006 and measured about 2,3 h of its light curve. The rotational period of this 162 diameter asteroid is 9,020 h. We used fotometrical R-filter and each exposure time was 60 s. The fotometric […]
