6 December, 1999 ---------------- Data type: "e" Magnetometer and acquisition system are operated by the Antarctic Division. I believe the instrument maybe an AGSO fluxgate and the acquisition system uses a 16-bit A/D. (RAM - 15/12/99) 5 September, 2000 ---------------- Files containing all calibration information for the fluxgate which is actually operated by ANTDIV were obtained from ANTDIV and can be found under the "dav" subdirectory of the "mag" account and is called "cal.dat". (RAM - 16/10/00) 29 Decmber, 2001 ----------------- The data being received had the sample period changed to 5 Hz at 0130UT at the station, however, this change was not duplicated in the "stn.dat" file, ie., the sample period in the "stn.dat" file remained at 1Hz . This has meant that the "raw" data has the incorrect value for sample frequency in the header line, ie., 1Hz, while the data in the file is actually sampled at 5Hz. The "standard" data has the sample frequency in the data file header corresponding correctly to the number of data points in the file, although the sample point selected for each second by the processing is not on the zero second mark. The change to the sample period was not realised until 14th January, 2002 due to the holiday period and hence the discrepany between the sample period in the "raw " data file header and the number of sample points has not been rectified. The sample frequency is expected to be set back to 1Hz after the campaign is over towards the end of January. (RAM - 16/1/02) --------------- 3 April, 2006 (ANTDIV/RAM) Telecommunications wish to advise of the following outage, currently affecting data circuits to Casey, Davis, Macquarie Island and Mawson. ------------- Outage Notification #1 ----------------------------------------- Time and date: from 10:30AM Monday 03/04/2006 Services affected: All data links between Kingston and CAS, DAV, MAW and MQI. Comments: Fault within Telstra hardware affecting our data circuits. ------------------------------------------------------------------------ ------ Telstra are currently investigating the fault, and we will advise on restoration of services as soon as possible. ------------------------------ 3 April, 2006 (ANTDIV/RAM) Telecommunications wish to provide update on the outage affecting data circuits to Casey, Davis, Macquarie Island and Mawson. Circuits to Casey, Davis and Mawson have been restored. Circuit to Macquarie Island is still unavailable. ------------- Outage Notification #2 ----------------------------------------- Time and date: from 10:30AM Monday 03/04/2006 Services affected: All data links between Kingston and CAS, DAV, MAW and MQI. Comments: Services to CAS, DAV and MAW restored. Services to MQI still unavailable. ------------------------ *********** 18 March, 2009 Data type: "M" Data stream changed from AGAD fluxgate magnetometer to SERC MAGDAS instrument. Davis AGAD fluxgate magnetometer was turned off on 1 March 2009. Data is coming via SERC Japan to IPS. The stn.dat files have been modified accordingly.
