from INTERMAGNET by the National Geophysical Data Center (NGDC), Boulder andingested into World Data Center A (WDC-A).6.3 Hourly mean valuesHourly mean values, centred on the UT half hour, are computed from the oneminute values. The data presentation is XYZF coordinate.6.4 Daily mean valuesvalues.Daily mean values, centred on the UT half day, are computed from the one-minute6.5 Monthly mean valuesMonthly mean values are calculated from the X, Y and Z daily mean elements forthe seven geomagnetic elements X, Y, Z, D, I, H and F. From 1991 to 1996 monthly meanwere reduced from Ancon Observatory (ANC)6.6 Mean annual valuesMean annual values are calculated from the daily mean values. Annual values arepresented in a separate table. The values are centred on the middle of each year. Graphicalpresentations of mean annual values are also included, but only for D, I and F components.From 1991 to 1996 mean annual values were reduced from ANC.7 INDICES7.1 K-indicesK indices for Huancayo are obtained using the K-indices Adaptive SmoothingMethod (KASM), accepted by IAGA. This software is provided by the Institute of GeophysicsPolish Academy of Science, Warsaw, Poland. The index values are determined from the Xand Y component and the K9 limit is 241 nT. The daily sum SK are the 8 K numbers, and thea K are determined from the K corresponding to table 7.1 with A K = Ʃ a K /8. K-indices are sentto INTERMAGNET of Paris FTP server.Range (nT) 0.0-2.4 2.4-4.8 4.8-9.6 9.6-19.2 19.2-34.0 34.0-58.0 58.0-96.0 96.0-160.0 160.0-240 > 240.0K 0 1 2 3 4 5 6 7 8 9a K0 3 7 15 27 48 80 140 240 400NOAA G-scale G0 G0 G0 G0 G0 G1 G2 G3 G4 G5Table 7.1 Range indices for HuancayoNOAA Space Weather Scale for Geomagnetic Storms (NOAA G-scale) wasintroduced as a way to communicate to the general public the current and futuregeomagnetic storms caused by gusts in the solar wind that blows by Earth. The scales havenumbered levels, analogous to hurricanes, tornadoes, and earthquakes that convey severity.They list effects at each level: G1 Minor, G2 Moderate, G3 Strong, G4 Severe, G5 Extreme.8 DATA DISTRIBUTION AND AVAILABILITYTables of hourly mean values of the magnetic elements are no longer published inthis series of publications.Apartado 130207, Lima 13, PerúTeléfonos (+51-1)317-2313 - Fax (+51-1)317-2312
Preliminary (Reported) one-minute digital data are sent by E-mail on a daily basis tothe INTERMAGNET GINs in Edinburgh, WDC for Geomagnetism of Kyoto andINTERMAGNET – Poland (IGF PAN - Poland).
