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)._x000D_
Since 2004 to 2008 the absolute observations were carried using two instruments:_x000D_
For (D,I) components was used a Bartington MAG 01H (with a Zeiss teodolit 010B)_x000D_
For total field (F) a ppm Geometrics G816 serie number 825
