The recent development of human space activity requires accurate space weather forecasting through the study of solar explosive phenomena and their origins. Such phenomena can endanger life due to the effects of high energy particles and radiation. The Solar Magnetic Activity Research Telescope (SMART) which was built in 2003, is a state-of-the-art instrument that combines high resolution H alpha full disk observations and vector magnetic field measurements. This allows us to investigate the development of magnetic activity and the mechanisms responsible for energy storage and release in the solar atmosphere.

SMART consists of four different telescopes with apertures of 20 or 25 cm. They are placed on a tower with a height of 16m.

T1: For H-alpha full disk observations

This telescope acquires solar H alpha full disk images at high spatial and temporal resolution thus enabling us to monitor any explosive events that take place at any position on the sun.

T2: For vector magnetic field measurements

Information about the three dimensional photospheric (vector) magnetic field can be obtained with this telescope. Vector magnetic field measurements are essential for understanding solar explosive events.

T3: For H-alpha/continuum high speed observations

Partial images with high spatial and temporal resolutions are useful to study the dynamic evolution of structures and the energy release mechanism of solar flares.

T4: Multipurpose telescope

This telescope is designed for obtaining partial H alpha images and measurements of the vector magnetic field. In magnetogram mode it can acquire partial frame images of the photospheric magnetic field with higher spatial resolution and quality than those of T2.
