Abstract. In
recent years in situ data have resulted in explosive growth in our knowledge
and understanding of solar-terrestrial processes. However, the space era began
only in the mid-20th century and thus in situ data alone is not enough for
analyses of the solar driven geomagnetic variations from decades to centuries.
The Russian network of magnetic and meteorological observatories provides one
of the longest data series. The magnetograms of St.-Petersburg (SPE,
1869–1877), Pavlovsk (SLU, 1878–1941) and Voeikovo (LNN, 1946–2016) provide a multi-year
series of continuous records of variations of the declination (D),
horizontal (H) and vertical (Z)
components of the geomagnetic field. We created an archive of the collection of
magnetograms as digital images and made these images available online. The
database also includes data for geomagnetic storms from the catalogues of
Pavlovsk (1878–1941) and Voeikovo (1947–1954) as well as data on the auroras
registered by 141 Russian meteorological stations in 1837–1909. Our database is
designed for providing web access to the Russian collection of historical
geomagnetic and auroral activity information. It
is targeted specifically for the research in various aspects of the space
weather and climate, including heliomagnetobiology. User is given an easy access
to the individual magnetograms at various zoom levels.
