Continuous observations of geomagnetic field run by Institute of Geophysics PAS
Jan Reda
Place of work:
- Parent organization: Institute of Geophysics Polish Academy of Sciences (acronym: IGFPAS)
- Head of Research Group for Geomagnetic Observations in Central Geophysical Observatory at Belsk, ~50km south-west of Warsaw
Work interests: - Methodology of geomagnetic observations: absolute measurements, recording of
variation of geomagnetic field, data acquisition for geomagnetic observations, data processing in geomagnetic observatories
- Practical aspects of magnetotelluric soundings
- Geomagnetic activity, e.g. indices of geomagnetic activity
- works in Definitive Data subcommittee of INTERMAGNET program,collection of definitive data and preparation of final compilation of yearly DVD containing data from all INTERMAGNET observatories (chairman of this subcommittee)
Institute of Geophysics PAS – main departments

BELSKSUWAŁKI
Research magnetic pulsations based
on the network of magnetometers located approximately on the magnetic meridian.
One per few months 1sec data
are transmitted to Tihany (MM100 centre)
Belsk - since 2005
Suwałki - since 2007
Close cooperation with Eotvos Lorand Geophysical Institute
Observation in frame of IMAGE network(International Monitor for Auroral Geomagnetic Effects)
HORNSUND
The prime objectives of IMAGE are to study auroral electrojets and moving two-dimensional current systems.
Hornsund since 1993
On average one per month 1sec data are transmitted to Helsinki (IMAGE centre)
Observations of Schumann resonance phenomena Continuous recording of two horizontal elements of
magnetic field and vertical element of electric field in the ELF frequency range
Sampling rate 100Hz
Continuous recording in Belsk and Hornsund
since 2005 and 2004 respectively.
Close cooperation with Geodetic and Geophysical Research Institute Hungarian Academy of Sciences in Sopron
HORNSUND (since 2004)
BELSK (since 2005)
NAGYCENK (since 1993)
Schumann resonance observations (Belsk, Hornsund)

Hornsund
Induction magnetometer
Field works
- Magnetotelluric or geomagnetic deep soundings (usually each year)
- Other field works as study of artificial magnetic disturbances caused by electric railway
