Exoplanet GJ436 observed and measured at Taurus Hill Observatory.
Star GJ436 (GSC 1984-1926) has a planet that has a size about the planet Neptune. It has a revolution time of 2.64 days, so it is very close to its mother star. The planet is very interesting due it has observed that is might have water in its atmosphere. Also there are estimates that there […]
The afterglow of the gammaray burst GRB080319B observed at THO (updated 21.3. 11:07).
The afterglow of the gammaray burst GRB080319B was observed 23 – 01 (finnish time) 19./20.03.2008 at Taurus Hill Observatory by the research team members Veli-Pekka Hentunen and Markku Nissinen. The observation was made 15 hours after the discovery of the GRB080319B. The measurements were made with the clear filter and with the photometric R -filter. The place of the GRB080319B […]
Exoplanet WASP-3b transit observed at Taurus Hill Observatory.
WASP-3b is a large gas giant that has a revolution time of 1.85 days. The mother star is GSC 2636-15. The radius of the planet is about 1.31 times the Jupiter radius. The temperature of the planet is about 1700 celsius degrees. The distance to the planet is about 727 light years. This planet was […]
Supernovae SN2008at and SN2008ax photographed.
Two supernovae was observed at Taurus Hill Observatory 7./8.3.2008. Observer: Veli-Pekka Hentunen. Supernova SN2008at is a Ia type of supernova. It was discovered by the Jack Newton anf Tim Puckett 2.3.2008. The maximum magnitude of the supernova was about 16.5 mag. Supernova SN2008ax is a II type ofsupernova. At the moment of the photographing it had a brightness of 15.6 magnitudes. This supernova […]
Supernova SN2008an photographed at Taurus Hill Observatory.
Supernova SN2008an is a Ic type of supernova that discovered from the galaxy UGC10936. At the maximum it had the brightness of 17.3 magnitudes. Taurus Hill Observatory´s research team member Veli-Pekka Hentunen photographed this supernova 2./3.3.2008
Three comets photgraphed at Taurus Hill Observatory.
Veli-Pekka Hentunen photographed three comets at Taurus Hill Observatory 2./3.3.2008. The weather was quite poor, the mist was present and few times Veli-Pekka has to stop the photographing due the rain. The temperature varied between -6 celcius degree and -10 celsius degree. Observer: Veli-Pekka Hentunen. Comet 46P/Wirtanen: Picture below is combine of 13×60 sec. exposured picture. No filters were used for photographing. The time of photographing was 19:22 […]
Supernova SN2008ak photographed at Taurus Hill Observatory.
Supernova SN2008ak was discovered from the galaxy UGC2519 12.2.2008 and it is a type II supernova. At the maximum it had the brightness of 17.0 magnitudes, but at the moment of this photograph it was much dimmer. The object photographed at Taurus Hill observatory 2./3.3.2008. Observer: Veli-Pekka Hentunen
Exoplanets HAT-P-3b and TrES-2b observed at Taurus Hill Observatory.
Research team member Veli-Pekka Hentunen measured the lightcurves of the HAT-P-3b and TrES-2b 26./27.2.2008 at Taurus Hill Observatory. He used clear filter for both measurement and the exposure times were 90 sec. The weather was quite foggy and the objects were quite low in the norhtern sky (about 20 to 30 degrees). The unfavourable seeing […]
Comet Wirtanen photographed by the Veli-Pekka Hentunen.
Comet 46P/Wirtanen photographed at Taurus Hill Observatory in the evening of 22.2.2008. The full moon made the observation a bit difficult, but still there is a quite bright object in the picture below. At the moment of the photograph the comet was about 28 degrees abowe the horizon. The clear filter was used for photographing and the exposure […]
