Taurus Hill Observatory research team manage to observe the after glow of the gamma ray burst GRB 140215A by using the remote telescope located in Auberry, California, USA. Team observed GRB about 1.5 hours and during that time the after glow dimmed very rapidly from the 17.00V magnitudes to 19.07CR magnitude.

Supernova SN 2014J photographed with DSLR -camera
Jari Juutilainen photographed the supernova SN 2014J 28.1.2014 with DSLR -camera without any automatic tracking. Supernova was bright enough to be observed from the sinlge image (f2.8, ISO3200, 1,3s). Here is Jari’s combined photo of the supernova and the galaxies that are in the same region of the sky.

The spectrum of the supernova SN 2014J measured
Taurus Hill Observatory research team measured the spectrum of the supernova SN 2014J. For measurement the THO research team used SBIG STT-8300M -camera, StarAnalyser100 spectrum lattice and Rspec-program. The image shows clearly the typical Ia-type of supernova spectrum, including the Si-II absorbtion line with wavelength of 6100 Angstrom. This is caused by fusion of the […]
Supernova SN 2014J photographed at THO
It has been a while since THO research team photographed supernovae. Here is a picture about the supernova SN 2014J, located in M82, taken by Veli-Pekka Hentunen in Taurus Hill Observatory. According to Veli-Pekka’s picture, the brightness of the supernova was about 10,92 magnitudes (CR, comparison star NOMAD1 1596-0106875).
Dim Nova Del 2013 observed
THO research team member Jari Juutilainen managed to photograph the Nova Del 2013 13.10.2013 despite it was quite dim, only about 10.5 magnitudes. In single photograph, the nova wasn’t visible, but when Jari stacked two photos, the nova was visible. More about Jari’s Nova Del 2013 observation can be found from www.pimennysmatkaaja.fi (in Finnish).
GRB130831A observed and photographed at THO.
THO reasearch team managed to observe and photograph the after glow of the GRB 130831A about 7 hours after Swift-telescope discovered it. Markku Nissinen and Harri Vilokki took photos that clearly shows the GRB. The exopsure times were 600 seconds and according the measurements the brightness of the GRB was about 18.01 magnitudes. The measurements […]
Nova Delphini 2013 Observations Summary.
Nova Delphini 2013 was one of the positive surprises of the late summer 2013. The maximum brightness of the nova was about 4 magnitudes and the best thing was that the nova was in very “good position” on the sky here in Finland. THO research team member Jari Juutilainen observed nova several times and here […]
Gamma ray burst GRB 120326A optical after glow was photographed.
Gamma ray burst GRB 120326A optical after glow was photographed by Taurus Hill Observatory research team with Nerpio T17 (Spain) remote telescope. The observation has beenpublished in GCN 13119 circular (Hentunen V.P., Nissinen M., Salmi T.).
Gamma ray burst GRB 111228A optical afterglow observed.
THO research team made observations with GRAS017 remote telescope about the gamma ray burst GRB 111228A optical afterglow. The brightness of the object was 18.7R magnitudes about 9,0 hours after the Swift -satellite discovered the GRB. This observation has been published in GCN 12754 circular. Observers: Markku Nissinen, Veli-Pekka Hentunen and Tuomo Salmi.
