Maglab has recently opened its new geomagnetic observatory of Kelčany in South Moravia.
The observatory is located 6 m underground where the temperature is highly constant (form 9°C in winter to max 13 °C in summer with negligible daily variations).

The magnetometer used in this observatory is a triaxial fluxgate manufactured by Maglab.
