The solar flares release energy that affect the near Earth environment and particularly a part of the atmosphere called ionosphere.

Through monitoring of the propagation of radio communication signals, this station aims at detecting some of the ionospheric effects resulting from solar flares. Those effects are known as Sudden Ionospheric Disturbances, or SID.

Real time SID Monitor data from Hlohovec....

Rondel in Bučany possibly served as a solar and lunar observatory.

8./9.XI.2003

During the night of 8th/9th November 2003 we observed Lunar Eclipse by photographic method. We obtained following three images using MIR 100/1100 teleobjective, exposure on film Fujicolor Superia X-TRA 400 ASA. At 1:09 UT was the Earth's shadow quite light and had a purple-red colour.

On 31th May 2003

we observed partial Solar Eclipse by photographic method. We obtained following images using MIR 100/1100 teleobjective during interval 3:42 UT - 4:16 UT.

On 7th May 2003 we observed Mercury Trasit by visual and photographic method. We also captured an VHS video record during contacts T3 and T4. Time received from the time signal DCF 77 Mainflingen (Germany) was included into the video frames.

Leonids in Hlohovec was observed in contrary conditions. Weather was changable and it was possible to observe only through gaps in the clouds. Moon was just one day before full phase, thus we were allowed to observe the brighter meteors only. ZHR was computed, but relative maxima occured approximately at 3:40 UT , 4:05 UT and 4:25 UT. The most remarkable maximum was at 4:05 UT. Photographic observation was performed during following intervals:

interval beginning (UT) end (UT) 1. 2:51 3:01 2. 3:20 3:34 3. 3:52 4:11 4. 4:12 4:41

using wide angle Flektogon 2,8/20 mm objective, exposed on film Agfacolor HDC (400 ASA). During 2:50 - 4:41 UT we observed several bright meteors with perceptible colours: 1 red a 3 green. We also observed following interesting evengs: 1 time 3 bright meteors at once and 6 times 2 bright meteors (~ 2 mag) at once. Meteors was comming in batches, always several together followed by short pause.
