1949 HMV data: D component in June too high by 1080 arcminutes. (fixed 2012-10-30)
1953 hour means: In WDC format dataset, there are two sets of values for month 6, Z component, and none for month 7. The second set of month 6 Z component values belong to month 7. [fixed 2011-08-25]
1953 hour means: In WDC format dataset, there are two sets of values for month 8, D component, and none for month 12. The second set of month 8 D component values belong to month 12. [fixed 2011-08-25]

BRAZIL
(ewan 22/01/2009)
Observatory instrumentation:
Variometer: La Cour Magnetograph / Töpfer-
Eschenhagen Magnetograph as backup System.
in addition
since 01.01.2009:
GSM-19 Magnetometers Console, suspended dIdD System
Absolute instruments: DI-flux (Zeiss theodolite with Bartington MAG01H fluxgate).
VPPM type Varian V75 / V85
PPM Elsec820
The INTERMAGNET variometer has (H,D,Z) orientation and from year 2004 to 2008 was a ring-core fluxgate magnetometer (by Narod). The ppm didn't work since 2003. This year 2009 a LEMI (417 by Korepanov) is working. We intend improve the VSS data, we're arriving two Overhauser magnetometer that were bougth, one of them will work as base line and another together with the variometer (Lemi-417).
Since 2004 to 2008 the absolute observations were carried using two instruments:
For (D,I) components was used a Bartington MAG 01H (with a Zeiss teodolit 010B)
For total field (F) a ppm Geometrics G816 serie number 825 |
