Solar Submillimeter Telescope, Radio telescope at Leoncito Astronomical Complex, San Juan Province, Argentina.
The Solar Submillimeter Telescope is a radio instrument with a 1.5-meter Cassegrain mirror system situated at the Leoncito Astronomical Complex in the high Andes. It observes the sun across two specific frequency bands to detect energetic activity and phenomena occurring on the solar surface.
The facility began making observations in April 1999 and entered regular daily operations in April 2001. A partnership between CONICET Argentina and Mackenzie University Brazil established the foundation for its ongoing research mission.
The telescope represents a point of connection between Argentina and Brazil, where scientists from both countries work together to observe the sun. This collaborative research site shows how international partnerships help advance our understanding of solar phenomena.
The telescope sits at high elevation in a remote mountain setting, which provides excellent conditions for observations but requires careful planning to visit. Access is restricted and arrangements must be made in advance through the research facility.
The instrument captures high-energy particles released during solar eruptions, with some observed patterns remaining unexplained by current solar physics theories. These puzzling observations help push scientific understanding forward and guide future research directions.
