Exoplanet CoRoTExo2 b is seventeenth exoplanet that is observed at THO.
Despite the light sky, Veli-Pekka Hentunen (one of the THO research team members) managed to photograph and measure the light curve of the exoplanet CoRoTExo2 b. This exoplanet dims its mother stars GSC 465-1282 light almost 40 millimagnitudes. The star is located in the Aquila about five degrees below the Altair. The star is about 12.6 […]
Supernova SNF20080720-001 photographed at THO.
Supernova SNF20080720-001 was discovered by the SN Factory in July 20. 2008. It is a type Ia and it was 16.6 magnitudes bright at the moment of the photographing. The supernova was faintly visible when Veli-Pekka Hentunen photographed it 30./31.7.2008 in Taurus Hill Observatory. The galaxy itself (IRAS 01026+3735) is also a very dim object. Observer: Veli-Pekka Hentunen
Noctiludent clouds season has started.
Noctiludent clouds are a clouds that are appr. 70-90 km high from the ground level in Mesosphere. Noctiludent cloud phenomena can be observed when the Sun is about 4 to 16 degrees below the horizon. Here in Finland noctiludent clouds are most common in July and in the beginning of August. Below are some noctiludent […]
Exoplanet researcher Gregory Laughlin visited in Taurus Hill Observatory.
Gregory Laughlin and his wife were guests of honour in the Cygnus 2008 -event. Laughlin is known as one of the exoplanet researchers that collaborates with the amateur astronomers. In the Cygnus 2008, Laughlin gave a lecture about the collaboration between the professional astronomers and amateurs. Taurus Hill Observatory has made exoplanet light curve measurements […]
Sixteenth exoplanet observed at Taurus Hill Observatory.
HAT-P-4b is sixteenth exoplanet that has beed successfully observed at THO. The measurements of the HAT-P-4b were made 10./11.5.2008 by the Veli-Pekka Hentunen and Markku Nissinen. The mother star, GSC 2569-1599, of the planet is F-class star that is larger than our Sun and the distance from the Earth is about 1010 light years. Planet is so called hot-Jupiter, that has […]
Fifteenth exoplanet, HAT-P-5b, measured at THO.
Exoplanet HAT-P-5b was discovered October 2007. It circulates the star GSC 2634-1087 that is about 11.9 magnitude bright. It is located in the Lyra about 1100 light years from the Earth. The star is only 0.16 times of the Sun in mass, but it is larger in diameter than the Sun. It has a spectrum […]
GRB080430 photographed at Taurus Hill Observatory.
The afterglow of the gammaray burts GRB080430 is clearly visible in the pictures that were taken at Taurus Hill Observatory by the Veli-Pekka Hentunen and Markku Nissinen. They used 600 sec. exposure times for clear and photometric R -filter images. The brightness of the GRB was, according the measurements, 19.2CR and 19.5R. The object was located in the coordinates RA […]
Supernovae SN2008P and SN2008bx.
Supernovae SN2008P and SN2008bx were photographed 24./25.4.2008 at Taurus Hill Observatory by the research team members Hentunen and Nissinen. SN2008bx was discovered 22.4.2008 by Tim Pucket. The supernova is quite bright, about 15.5 magnitudes. The type of the supernova is at the moment still unknown. SN2008bx SN2008P was discovered 23.1.2008 by Alessandro Dimai. This supernova is a […]
