Veli-Pekka Hentunen measured the lightcurve of the asteroid 93 Minerva in Taurus Hill Observatory 24.-25.12.2006 23:00-05:00. Veli-Pekka used R -filter and 120 sec. exposure (per picture) for photometric measurements. The comparison stars used in this measurement were GSC1423-528 (C1) and GSC1423-568 (C2). The weather was damp and little foggy. Due this and the fact that the correction lens […]
Asteroid 7 Iris was photographed in Taurus Hill Observatory 27./28.11.2006 by Markku Nissinen and Veli-Pekka Hentunen. The asteroid is now about 7,2 magnitude bright object and it is 130 million kilometers away from the Earth. This picture is taken with clear filter and 15 sec. exposure. (Tämä uutinen suomeksi)
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 […]
Observers: Veli-Pekka Hentunen and Markku Nissinen 23 April 2006.
Following observations are made from Geometria 16/17 March 2006 and 26/27 March 2006 in THO. Observations are made in the night of 2/3 April 2006 from Eurynome. Observers: Veli-Pekka Hentunen and Markku Nissinen. (Tämä uutinen suomeksi)
The CCD-picture is taken at 100s exposure. The asteroid 23187 (2000 PN9) draws a line in picture, because it has so big apparent movement in the sky. CCD-picture is taken 7.3.2006 evening. Observer: Markku Nissinen.
