Abstract:
Presently, in the era of Internet communication the preliminary time series (INTERMAGNET’s reported data) acquired in geomagnetic observatories are available in near-real time, while the final absolute time series (definitive data) are disseminated with many months delay, being subject to many checks. This paper reports the quasi-definitive geomagnetic data obtained in Panagyurishte observatory in 2012, prepared in the form of local geomagnetic indices and absolute time-series of hourly mean values plots. Verification of data quality is performed according to “IAGA guide for magnetic measurements and observatory practice”.

Keywords:
PAG observatory, geomagnetic variations, geomagnetic activity, hourly mean values
