Asteroid 37 Fides spins around its axel once in every 7,3 hours. In Taurus Hill Observatory we measured about five (5) hours from this one spin. The lightcurve below is a result of about 200 separate R -filter -pictures (60 sec. exposure in each picture). This measurements was made in 11.-12.1.2007 and the sky was clear […]

SN2006nr observed in Taurus Hill Observatory.
SN2006nr was observed 29/30.12.2006 night at THO. Observers Veli-Pekka Hentunen and Markku Nissinen. Supernova SN2006nr had been discovered by Tim Puckett and A. Pelloni at October 26 2006. Then it was around 16 magnitudes. Now it was much dimmer, about 18.4 magnitudes. SN2006nr:
Supernovae SN2006st and SN2006su photographed in Taurus Hill Observatory.
Supernovae SN2006st (about 18,4 mag.) and SN2006su have been photographed 28/29.12.2006 night. Observer: Veli-Pekka Hentunen. (Tämä uutinen suomeksi) SN2006st: SN2006su:
Exoplanet HD80606b transit missed due the clouds.
Exoplanet HD80606b is located in the “Big Bear” and its transit lasts about 17 hours. You can observe the transit in four month periods and this time the transit occured in the darkest time of the year here in Finland. The weather was promising, but after a hour the weather turned out to be very […]
Asteroid 93 Minerva lightcurve measured in Taurus Hill Observatory.
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 […]
Comets 4P/Faye and C/2006 L1 (Garradd) observed in THO.
Comets 4P/Faye and C/2006 L1 (Garradd) were observed in THO 15.12/16.12 night. Observers: Veli-Pekka Hentunen, Markku Nissinen, Henri Taino and Mari Laitinen. (Tämä uutinen suomeksi) 4P/Faye: C/2006 L1 (Garradd):

HD209458b exoplanet transit observed in THO.
HD209458b was the first exoplanet that was observed by amateur (Nyrölä, Finland; 2000). Taurus Hill Observatory’s observing group members Veli-Pekka Hentunen and Markku Nissinen photographed this exoplanet transit 27./28.11.2006. Due the humidity it was very difficult to make good measurements. Also the lack of the good comparison stars in field of the CCD -cell field made reliable measurements challenging. The comparison stars […]
