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, […]
The Europlanet Science Congress (EPSC) is the major European meeting on planetary science. In light of the COVID-19 situation, EPSC 2021, originally planned for Helsinki, will be held as a virtual meeting. EPSC2021 is the second time that EPSC has been held as a virtual meeting. The virtual meetings are likely to play an increasingly important role in supporting […]
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 […]
The clear weather that lasted for a few nights last week made it possible to make observations at the Härkämäki Observatory. With the observation deck of Celestron, a light curves of seven different exoplanets were observed from 7 to 10 December 2020. The SBIG ST-8XME CCD camera with a photometric R-filter was used for the […]
Comet C/2020 M3 (ATLAS) observerd at THO 03:14 Finnish time. Combined photo of 15 x 80 sec R-filter.
