The supernova SN 2009bw that was discovered 27.3.2009 at Taurus Hill Onservatory has brightened up since the discovery. 1.4. it had a brightness of 14.7R measured with the photometric R -filter. It is assumed that this is the maximum brightness for this supernova. SN 2009bw has been researched carefully with e.g. Swift -satellite. One research reslut […]
Exoplanet HAT-P-8b transit observed at Taurus Hill Observatory.
Exoplanet HAT-P-8b was discovered December 2008. It is located in the Pegasus about 750 light years from the Earth. Planet is so called Hot Jupiter and it has a period of three days. The size of the planet is about 1.5 times the size of the Jupiter. THO research team observed half the transit of the HAT-P-8b […]
Comet C/2009 E1 (Itagaki) photographed at THO.
Comet C/2009 E1 (Itagaki) is very difficult object to photograph due it is in very low altitude in the western sky just few moments after the sunset. The comet is also quite dim and it is visible only with the large telescopes. THO research team photographed the comet 26.3.2009. Observers: Veli-Pekka Hentunen and Markku Nissinen.
Supernova SN 2009bw discovered at Taurus Hill Observatory.
Taurus Hill Observatory research team managed to discover a supernova SN 2009bw 27/28.3.2009. This is the seventh supernova that has been discovered at THO. This time the supernova was discovered from the galaxy UGC 2890. The discovery was published in the Central Bureau of Astronomical Telegrams circular CBET 1743. The discoverers of the SN 2009bw were […]
Hentunen and Nissinen as one of the discoverers of the supernova SN 2009bt.
Taurus Hill Observatory research team members Veli-Pekka Hentunen and Markku Nissinen were successful when they discovered supernova SN 2009bt with Cortini, Jacques and Pimentel 24.3.2009. Hentunen and Nissinen were the first ones who measured the correct location of the SN 2009bt. This supernova is the first one that has been discovered with the THO Celestron C14 -telescope. […]
The light curve of the exoplanet GJ436b measured.
The reasearch team of the Taurus Hill Observatory managed to measure the light curve of the exoplanet GJ436b 24.3.2009. This was fourth time the research team measured the light curve of this interesting exoplanet. The reason why GJ436b is so interesting is that there are some variations in the measurements that could indicate the precense […]
The gamma-ray burst GRB 090313 observed.
The gamma-ray burst GRB 090313 was observed by Markku Nissinen 13.3.2009 about one hour after the discovery of the GRB. Markku used the GRAS-04 telescope that is sited in Mayhill, NM, USA. The exposure times that Markku used were 300 sec., 360 sec. and 600 sec. Below are the results. obs midpoint(UT) exptime mag(CR) mag.err2009-03-13 10:14:41 360 […]
C/2007 N3 (Lulin) is bright comet in the sky.
Comet C/2007 N3 (Lulin) has been getting brighter and brighter and THO research team photographed this comet 25.2.2009. At the time of photographing the comet was so bright that in good conditions it might have been possible to make naked eye observations from the comet.
SN 2009an photographed by the research team.
In the CBET 1707 there is a text “independent discoverers, reported following the posting to CBAT unconfirmed objects page”. These independent discoverers are Mikko Päivinen and Petri Kehusmaa. As a discoverers the CBET 1707 says Cortini, Antonellini from Italy. Markku Nissinen and Veli-Pekka Hentunen photographed the confirmatrion image of the discovery (many others did it […]
Supernovae SN 2008ip and SN 2008N.
Supernovae SN 2008ip and SN 2008N are very interesting supernovae for the researchers. This is due they both are rare type of supernovae. Both supernovae have been observed quite long time at THO by the research team. Here are photographs that are taken 25/26.2.2009.
