'�point�for�'� ����km�. Similar networks are created
in most European countries. The works of this sci-
entific branch are coordinated by MagNetE (Mag-
netic Network in Europe) organization, which was
founded in Potsdam in 2003. For accurate reduc-
tion of geomagnetic field components it is neces-
sary to refer the RS measurements data to the con-
tinuous magnetic variation observations that are
carried out on close by magnetic observatories (MO)
or set of MO. There are 3 MO in Ukraine “Kyiv”,
“Lviv” and “Odesa”, besides for the reduction accu-
racy increasing we can use the data of neighbou-
ring countries MO such as “Belsk”, “Tihany” etc. as
well as the data of permanent magnetic variation on
geophysical stations such as “Nyzhnje Selysche” etc.
The main task of magnetic RS measurement
consists in creating the maps of normal geomag-
netic field components and theirs secular variation
(SV) rates. Alongside of geomagnetic fundamental
problems decision the results of RS measurement
allows to perform reduction of different time mag-
netic data to common epoch and unified normal field
level. This is very important for creation of aggrega-
ted anomalous field maps of large areas. The results
of RS magnetic measurements may be very useful in
navigation and topographic mapping where magnetic
declination D and its yearly changes are given.
Actuality of RS network magnetic measurements
and creating the newest maps of normal magnetic
field as well as its SV rate on the territory of Ukraine
is emphasized also because of appearing of SV rate
focus at the end of XX century in the Eastern Eu-
rope. The appearing of this focus makes it more
difficult to use the worked out local anomalous mag-
netic field models and investigate this field tempo-
ral changes for tectonic magnetic investigations as
well as for geophycical exploration. Comparison of
SV rates calculated due to model IGRF-2005 with
rates obtained on MO of Europe reveal as notice-
able distinctions of theirs special structures and
morphology of time series between them as well
[Maksymchuk et al., 2010].
We did follow the international recommendations
[Newitt et al., 1996] when selecting the place of RS
founding and performing measurements of magne-
tic field components. The scalar of geomagnetic field

vectors were measured by proton magnetometers
with sensitivity 0.1 nT. Magnetic declination and in-
clination (I) were determined with ferrosonde mag-
netometer mounted on demagnetized theodolite of
1 arcsec scale accuracy. The reductions of mag-
netic field X-, Y-, Z-components were done to mid-
dle of observation years epochs and to common
epoch 2005.5 as well. These reductions were per-
formed referencing the data of permanent observa-
tion of MO “Belsk”, “Kyiv”, “Lviv”. Standard devia-
tions of obtained results are in the range from 2 nT
to 3.5 nT for X-, Y-, Z-components and lesser then
30 for I and 50 for D. These results were summa-
rized in catalogue of Ukrainian RS for the 2005.5
epoch. We also created a set of maps for geomag-
netic field components.
Comparison of components values that were
obtained on Ukrainian RS network with the same
components calculated due to IGRF-2005 model
shows, that differences for linear (X, Y, Z) compo-
nents lie in the range from several to several hun-
dreds of nT. Apparently these differences are caused
mainly by effect of magnetic anomalies localized in
the Earth’s crust. The map of magnetic declination
D (isogons) has a particular applied interest. Such
map due to 1st cycle of Ukrainian RS network mea-
surements is shown on Figure. The values of D,
reduced to epoch 2005.5 on the territory of Ukraine
lie in the range from 4 in the western region to 8 in
the eastern region. The isogons shown on Figure
noticeably differ from the same calculated by mod-
el IGRF-2005. Unlikely to model isogons the ob-
served ones are of very complicated configuration.
One can easily distinguish several anomalies of re-
gional scale on the background of global trend. The
general features of isogons distribution configura-
tion are in concordance with tectonic structure and
anomalous magnetic field of regional scale.
Conclusion. The RS network creation on the ter-
ritory of Ukraine allows make use of the obtained
data in process of new generation IGRF model con-
struction. Even results of 1st cycle measurements
may be useful as for IGRF model more precise de-
finition and for tectonomagnetic investigations as
well. Undoubtedly it is necessary to fulfill the next
cycle of measurements on the created RS network
and if it would be possible to enlarge the number of
RS.
