4 Stations StationGeog. Lat. [°S]Geog. Lon. [°E]Local Time [hr]L-Shell Macquarie Island54.5159.0UT + 115.4 Mawson67.662.8UT + 49.1 Davis68.678.0UT + 514.7 Casey66.2110.3UT + 7- Scott Base77.9166.8UT + 11- Search-coil induction magnetometers. Data are typically sampled at 2 Hz (up to 8Hz for campaigns). Noise of 0.5 nT peak-to-peak at 5 mHz. 6 dB/octave frequency response to 0.2Hz, then constant with frequency. Daily calibration between 16:30 – 16:40 UT. Timing linked to GPS. Accurate within 50 ms. Data recorded continuously from 1994. H and D components recorded. Data are currently available by request to: brian.fraser@newcastle.edu.au. Summary dynamic spectra are available. Data must be calibrated if physical units [nT] are required.
