ABSTRACT
This contribution presents application of ISWI
International Programme in the conditions of
Slovak institutions, scientific focus of which
includes among other fields of observational and
research work also analysis of space weather
processes. Particular attention is paid to
providing scientific knowledge to students and
the general public.

• Patrol measurement of the green (530.3 nm,
  FeXIV)
• and red (637.4 nm, FeX) coronal emission lines
• intensities, short-term oscillations in these
  lines.
• It is done at Lomnický štít coronal station,
  2634 m
• above sea level with a 20 cm coronagraph with
• spectrograph
• Monochromatic observations in the green corona
• started in 2007
• Main target long-term variation of the green

• registration of solar flares
• J. Karlovský (Hlohovec) a R. Šlosiar (Bojnice)
  constructed their own prototypes of SID monitors,
  which are installed in Bojnice and in the
  Observatories Hlohovec and Parti-zánske. J.
  Karlovský constructed also a SuperSID
  monitor.Real-time data

• Neutron monitor at Lomnický štít high-altitude
• laboratory, 2634 m above sea level
• Participation in several space projects,
  development
• of instruments installed onboard the
  satellites
• - IEP SAS analyzes earlier energetic particle
  
• measurements on satellites Active, CORONAS-F,
• Interball-auroral and tail (Russian
  satellites)
• energetic neutral atom measurements on TC2
• satellite methodical works were done for
• Venus-Express magnetometer.
• - IEP SAS continues works for future
  measurements in space by participation in
  development of part of the plasma instrument for
  ESA BepiColombo mission for Russian RadioAstron
  mission and supporting works started for the
  project JEM-EUSO.
• Space Research Center influences of Space
  Weather, center of excellence in eastern
  Slovakia. Three institutes, namely Astronomical
  Institute of the Slovak Academy of Sciences in
  Tatranská Lomnica (main institution), Institute
  of Experimental Physics of the Slovak Academy of
  Sciences in Košice and P.J. Šafárik University in
  Košice (partner institutions) are constituting
  the Centre. With the help of the support by EU
  (2009-2013)- experimental and computational
  basis for various ground based and satellite
  measurements will be updated
• - new experiments will be established.

SUNSPOT OBSERVATIONS
Basic daily patrol observations of sunspots are
currently carried out in a network of 18
observatories and individual observers (including
members of the Slovak Union of Amateur
Astronomers). National centre for sunspot
observations is in the Astronomical Observatory
and Planetarium Prešov.

GO Hurbanovo is member institu- tion of the
INTERMAGNET Network for geo- magnetic
measurements
Sunspot numbers observed in Slovakia (1964
2008, 44 years with 106 971 individual
observations.
ISWI INSTRUMENTS
In the near future will be installed in Slovakia
in the frame of the ISWI instrument deployment
program the following instruments two SuperSID
monitors for registration of solar flares (both
in the SCO Hurbanovo and the Astronomical
Observatory in Rimavská Sobota) and one radio
spectrometer E-CALLISTO (in the SCO Hurbanovo).
EDUCATION AND PUBLIC OUTREACH

• Most of the National ISWI committee members
  have also teaching
• activities.
• SCO in Hurbanovo organizes a two-years course
  of astronomy at
• high-school level including lectures on solar
  physics
• and space weather.
• Astronomical observatories and planetaria in
  Slovakia perform in
• general guided tours, training of amateur
  astronomers and students,
• organize public astronomical events, summer
  programs, lectures
• and competitions, publish brochures, posters
  and other astronomical
• material for visitors, etc..
• AI SAS in Tatranská Lomnica organizes seminars
  for teachers,
• guided tours, Open House days , etc.
• SOME ISWI ACTIVITIES
• SCO in Hurbanovo organizes biannual national
  solar physics
• meetings with participation from abroad. Last
  one was held
• in June 2010 and the next meeting is planned
  for 2012.
• AI SAS in Tatranská Lomnica has suitable
  facilities for organisation of international
  conferences
