The first exoplanet light curve transit of this fall’s observation period was measured at Taurus Hill Observatory 30.8.2021. The target was HAT-P-10b / WASP-11b. The transit was exactly as predicted, the duration of the transit was about 160 min and the dimming of the parent star was about 25 mmag.
EPSC, or Europlanet Science Congress, 2021 will be held online, as in the previous year. Taurus Hill Observatory observations will be presented again this time as part of the ODAA5 session on Friday, September 24th. It is not possible to present a typical scientific poster in a virtual conference, but now, for the second year […]
The May Day party continued at the Taurus Hill Observatory, when three comets were spotted on 1 – 2 May 2021 at 00.35-02.00 Finnish time: C / 2020 R4 (ATLAS), C / 2020 T2 (Palomar) and C / 2017 K2 (PANSTARRS). In the pictures, the north is at the top and the east is on […]
An alternative celebration of COVID “vappu” (May Day), the exoplanet observation at the Taurus Hill Observatory 30.4. – 1.5.2021 from 23.40 to 02.45 Finnish time. The transit duration of the exoplanet Qatar-1b was 97.2 min and the dimming was 25.0 mmag. Happy May Day to all THO fb group members!
Comet C/2020 R4 (ATLAS) photographed at Taurus Hill Observatory on April 28, 2021 at 23:53 Finnish time. A sum image of ten individual images and a single image with an R filter were taken. Exposure in a single image is 80 seconds. The size of the image in the sum image is about 12 ‘x […]
A rare week in April. Seven consecutive clear nights. The dark moment of the night still lasted so long that the light curves of the exoplanet transits could be well measured. During the week (April 14 – April 20, 2021), the Taurus Hill Observatory measured the light curves of nine different exoplanets. For two nights, […]
Past few weeks have been good for fireball observations and THO all sky camera has photographed a few of them. Below are the latest observations.

The target exoplanet was the TESS satellite candidate TOI1455.01b. The timing of the transit was about an hour earlier than predicted, so the transit was close to not being included in the light curve. The measured length of the transit was 143 min, which is about 30 min shorter than predicted. The dimming caused by […]
The high-quality all sky camera has now finally been installed in Castle of Clouds (Finnish as Pilvilinna) that is private amateur observatory at the THO site. The camera has a resolution of six megapixels and produces a color image for the Warkauden Kassiopeia and THO websites every few minutes. The camera pole has been turned […]
