Description
Hourly mean magnetic field data determined for magnetometer data from the Pruhonice station (IAGA Station Code: PRU). The field observations that have been corrected for possible errors in timing, calibration, sign, transcription, omission, and misunderstanding. The hourly mean is calculated using data from the beginning of the hour to the end.
