Results of Geomagnetic Observations: Belsk, Hel, Hornsund, 2018
Author(s): Reda J., Neska M., Wójcik S., Czubak P.
This publication contains basic information on geomagnetic observations carried out in 2018 in three Polish geophysical observatories: Belsk (BEL), Hel (HLP), and Hornsund (HRN). All these observatories belong to the Institute of Geophysics, Polish Academy of Sciences. Observatories Belsk and Hel are located on the territory of Poland, while Hornsund is in Spitsbergen archipelago, under Norwegian administration.In 2018, like in the previous years, the Belsk, Hel, and Hornsund observatories have kept a close collaboration with the world network of geomagnetic observatories INTERMAGNET. The Belsk Observatory joined INTERMAGNET in 1992, Hel in 1999, and Hornsund in 2002.
BOOK OF EXTENDED ABSTRACTS. “Electromagnetic ULF/ELF Fields on Earth and in Space” Conference, Warsaw, Poland, 3-5 July 2019
Editor(s): Kułak A., Odzimek A.
A common topic of the conference are issues related to physics and geophysics of naturalsystems generating fields of frequencies in the ULF (Ultra Low Frequency – 0.003 to 3 Hz) range and ELF (Extremely Low Frequency – 3 to 3000 Hz) range. In the range below 3 Hz, atypical geophysical division of the pulsation phenomena in the Pc1-Pc6 ranges was used. Currently, after the International Telecommunication Union (ITU) introduced a new division of frequency bands, there was chaos, because the former ELF range was divided into three ranges, and one of them is called a ULF range. The division currently used includes the following bands: ELF (Extremely Low Frequency – 3 to 30 Hz), SLF (Super Low Frequency – 30 to 300 Hz) and ULF (Ultra Low Frequency 300 to 3000 Hz).
