The Solmirus ASIVA provides cloud cover data to world class observatories around the globe.



The Solmirus ASIVA is a must-have instrument for astronomical observatories. The Solmirus ASIVA provides cloud cover data and sky conditions to world class observatories around the globe, and can be used for scientific and automation tasks for a wide range of observing applications.

The ASIVA provides observatory operations with valuable data about sky quality, cloud cover and a range of sky measurements. ASIVA’s thermal IR imager has the distinct advantage of directly detecting emission from clouds rather than relying on scattered light or obscured starlight, thus providing consistent and reliable information under a wide variety of conditions. ASIVA’s unique up-looking all-sky infrared lens captures unobscured hemispherical images, a critical aspect of the instrument’s cloud cover, sky quality determination, and predictive capabilities. Furthermore, the ASIVA’s visible camera is a highly capable cooled CCD. The addition of an ASIVA to an observatory enables efficient scheduling, improved data quality, and telescope automation.

Notable ASIVA characteristics for Astronomers:
  • Coadding cabailities of IR images for improved Signal-to-Noise
  • Customizable multi-filter analysis in both the infrared and visible part of the spectrum grants flexibility and coverage to the user and provides the opportunity to explore differing wavelength-dependent atmospheric characteristics
  • Small cadence time supports close to real-time reporting
  • Production of high-resolution 16 bit images
