Multiwave Station of Solar Monitoring
is known that phenomena of solar activity have a greater influence
on processes in magnetosphere and ionosphere of the Earth, on terrestrial
weather conditions, health of people. It is necessary to take the
activity into account for studying the problems of human ecology
and environment. Modern station of solar monitoring provides with
data the monitoring near-Earth space, radio communications, servicing
the computer networks, electric networks, pipe-line transport. Data
on solar activities are necessary for public health; they are used
during cosmic projects.
of solar monitoring (SSM) on the base of the specroheliograph of
Astronomical observatory of Kharkiv State University and CCD photo
sensors allows to obtain digital images of the Sun regularly in
any spectral band from 300 to 1200 nm with periodicity 0.5-2 minutes.
In case of need after simple modernization it will be possible simultaneous
obtaining images in several spectral ranges.
the monitoring mode digital images of the Sun are processed in real-time
regime, classified and put to the electronic databank. Consumers
(scientists, interested organizations, astronomy amatours, observations
requesters, etc.) can obtain the data from the databank via Internet.
main purpose is solar activity monitoring. It is planned to carry
out observing of the Sun simultaneously in the helium infrared line
(1083 nm), the Balmer continuum of hydrogen (364 nm) and the H-alpha
hydrogen line (656.3 nm) with periodicity 5-10 minutes (Belkina
at al., 1996).
in the helium infrared line contain information about coronal holes
(sources of solar winds) and other objects, which can be observed
from space instruments only. Today only Kitt-Peak observatory (USA)
regularly obtains such images.
line observations are the most available way to fix solar flares
and explosive processes in dark filaments and prominences. This
allows to get data for the forecast of near-earth space condition.
obtaining in Balmer continuum is a new type of solar observing.
It allows for the first time to obtain data about macroscopic heterogeneity
of solar plasma density, about the statistics, dynamics and morphology
of areas with increased electronic density (Kurochka
at al., 1997).
observations in these spectral ranges with high time resolution
allow to study the evolution of chromospheric flares and quick processes
on different heights of solar atmosphere.
allows to obtain in principal new data on physical characteristics
of solar atmosphere and its activity, and to raise forecast quality
for solar flares and other types of the solar activity.
Easy tuneability. (It is possible to observe the Sun in any
spectral range from 300 nm to 1200 nm in the monochromatic light.
Band width is 0.0024 nm.)
- The Possibility of observations in several spectral bands simultaneously.
- High time resolution. (Full image (1000x1000) of the Sun
is obtained during 0.5-2 minutes.)
- The Spatial resolution is limited only by the atmosphere (approximately
- Data processing and formalization are performed in real-time regime.
- Round-the-clock access to data through Internet.
- Carrying out the custom-tailored observations.
