TrES-3 (GSC3089-929) located 800 ly away in the constallation Hercules is a little smaller star than Sun. It has an exoplanet with an orbital period of only 1.306 days and so it is one of the shortest orbital period of the known exoplanets. Semimajor axis of TrES-3 exoplanet is 1.295 Rjup and it diminishes light of its host star even […]

Exoplanet XO-2b transit observed at THO.
The K dwarf star XO-2 (GSC3413-5) has an exoplanet with an orbital period of 2.616 days and mass 0.57 Mjup. The host star XO-2 has a common proper companion with 31“separation and these stars are nearly identical. The distance of this object is about 486 ly. We observed XO-2b exoplanet transit first time at Taurus […]
Supernova SN2007gr observed in THO.
In Perseus constellation is located galaxy NGC1058. Now there is the third brigthest supernova in this year. Supernova’s type is Ib/c so it is th eend of a very hot giant star. We have taken 2x60s unfiltered CCD-images at 20th/21st of August for this combined picture. Observing team: Veli-Pekka Hentunen, Markku Nissinen and Veikko Kauhanen. […]

Blazar OJ287 observations made in Taurus Hill Observatory.
Blazar OJ287 is one of the most important observational objects for Tuorla Observatory. Taurus Hill Observatory research team has made brightness observations about the OJ287 once a week from December 2006 to mid of May 2007 (total 21 times). OJ287 is an Active Galactic Nuclei (AGN) that is located about 4,3 billion light years from Earth. There […]
