YEARBOOK – HUANCAYO GEOMAGNETIC DATA 2009
1 INTRODUCTION
This publication contains basic information on geomagnetic observations carried out during 2009 in the Huancayo Geomagnetic Observatory (HUA), which belongs to the Geophysical Institute of Peru (IGP).
In 2009, like in the previous years, the Huancayo Geomagnetic Observatory has kept a close collaboration with the International Real-Time Magnetic observatory Network (INTERMAGNET), which Huancayo Geomagnetic Observatory had joined to in 2003.
2 DESCRIPTION OF THE HUANCAYO GEOMAGNETIC OBSERVATORY
The observatory was established in 1919 by the Carnegie Institution of Washington, and it began to acquire continuously geomagnetic records since March 1st 1922. The Geomagnetic Observatory is located some 13 km NW from Huancayo city. The Absolute house “main pier” is situated in latitude 12º 02' 28.69'' south and longitude 75º 19' 14.11'' west, at an elevation of 3314 meters above sea level (3336 m. WGS 84).
The Geomagnetic Observatory consists of 4 houses: Absolute house, variometer house, one laboratory house, operations office and a guest house.
Huancayo Geomagnetic Observatory is an INTERMAGNET Magnetic Observatory (IMO) standard, and it is equipped with magnetometers with accurate time control, residing at the magnetic observatory site, having full absolute control.

3.1 DI-Flux
Absolute observation were carried out on a regular basis by means of a DI-flux magnetometer (or Declination and Inclination Magnetometers) for measuring the angles D and I. Measurements are obtained by operating the theodolite mounted probe in the null mode.
The total magnetic field intensity, F, was measured by means of Proton Precession Magnetometer. The absolute values H, X, Y and Z were then derived from:
H = F cos ( I ) (1)
X = H cos ( D ) (2)
Y = H sin ( D ) (3)
Z = F sin ( I ) (4)
Were H, Z and F are field values at the time of the I measurement. X and Y are field values between D and I time.
DI-flux at Huancayo Geomagnetic Observatory uses a Bartington MAG-01H fluxgate sensor mounted on Carl Zeiss-Jena O10B non-magnetic theodolite.
The DI-flux consist of a CARL ZEISS non-magnetic theodolite model THEO 010B, with a single-axis fluxgate sensor mounted on top of the telescope and magnetometer electronics from Bartington. The DI-flux is considered to be an absolute instrument, which means that the angles measured by the instruments do not deviate from the true values of D and I. This is achieved by using an observation procedure which eliminates the unknown parameters such as sensor offset, collimation angles and theodolite errors.

3.2 Barringer M-234 and RFP-523 Proton Magnetometer
We have a Barringer M-234 proton magnetometer with sensor installed to 23 meters NW direction from principal pillar E-2, and the second RFP-523 proton magnetometer with sensor installed to 32 meters NWW direction from principal pillar E-2.
3.3 F pillar corrections
At Huancayo Observatory D and I are measured on pillar No. E-2 in the Absolute House, and F is obtained from an Barringer proton magnetometer which is located at 23 meters NW. Differences on F is measured at regular intervals to reduce the F gradient between proton magnetometer and the main pillar E-2:
FMAIN PILLAR = FBARRIGER/RFP-523 +∆F BARRINGER/RFP-523 TO MAIN PILLAR (8)
The values adopted for the year are:
∆F BARRINGER TO MAIN PILLAR = -4.7 nT (9)
∆F RFP-523 TO MAIN PILLAR = -1.5 nT (10)

4 REFERENCE MAGNETOMETERS
The IGP maintains reference magnetometers for declination, inclination and total intensity at Huancayo Geomagnetic Observatory where they are use to calibrate the variometers periodically. DI-flux magnetometer is used as both the declination and inclination reference and an Barringer M-234 Proton magnetometer is used as the total-field reference.
Regular inter-comparisons are performed at IAGA workshops on Geomagnetic Observatory Instruments, Data Acquisition and Processing relate the Peruvian reference magnetometers to international standards. Absolute instruments used at Huancayo Geomagnetic Observatory are periodically compared with the reference magnetometers, sometimes through subsidiary traveling reference instruments.
Results identified as final in this report indicate that absolute magnetometers used to determine baselines have been corrected to international standards.

vertical-intensity (Z) variometers and one photographic recorder made by Otto Toepfer and Son, Potsdam. Because of the frequent and large fluctuations in H and loss of trace during times of magnetic disturbance, a La Cour low-sensitivity H variometer was installed as an adjunct to the Eschenhagen equipment in April, 1937. It was mounted on a specially constructed bass support on the north edge of the variometer pier of the Eschenhagen apparatus, adjacent to the H variometer, the position of which is noted in figure 2 (D). Control-time is with an electronic clock made by Oscar Veliz, Peru. From 1922 to 1997 was used as the principal magnetograph and from 1998 to 2009 was used as backup variometer. On January 01, 2010 at 00:00:00 hours UT, this instrument was stopped after to work for 88 years, for to be modernized its photographic record system.

6.2 One-minute mean values
One-minute mean values, centred on the minute, were calculated by applying the Gaussian coefficients to a series of 19 samples of 5-second data. For a filter output values to be centred on the minute, the first coefficient was applied 45 seconds before this minute and the last coefficient was applied 45 seconds after the minute.
Preliminary 1-minute time series are available in near real-time on the Geophysical Institute of Peru website. They are also sent to the Edinburgh INTERMAGNET geomagnetic information node (GIN) and made available on the INTERMAGNET website as reported data.
Adjusted 1-minute mean values in X, Y, Z and F, are sent to the Edinburgh INTERMAGNET GIN and made available on the INTERMAGNET website as adjusted data.
Definitive 1-minute mean values in X, Y, Z and F, and hourly mean values are submitted annually to Paris INTERMAGNET GIN. Under agreement with the National Oceanic and Atmospheric Administration (NOAA) USA, these data are then obtained directly
