A New Method to Estimate Cloud Cover Fraction over El Leoncito Observatory from an All- Sky Imager Designed for Upper Atmosphere Studies
(IOP Publishing, 2013-01)
A method for determining cloud cover fraction over El Leoncito Observatory (31.8°S, 69.3°W) is presented. Data from an all-sky imaging system, designed to measure nightglow originating from the mesosphere and thermosphere, ...
The all-sky automated survey for supernovae (asas-sn) light curve server v1.0
(2017)
The All-Sky Automated Survey for Supernovae (ASAS-SN) is working toward imaging the entire visible sky every night to a depth of V similar to 17 mag. The present data covers the sky and spans similar to 2-5. years with ...
The great observatories all-sky lirg survey: herschel image atlas and aperture photometry
(2017)
Far-infrared images and photometry are presented for 201 Luminous and Ultraluminous Infrared Galaxies [LIRGs: log (L-IR/L-circle dot)= 11.00-11.99, ULIRGs: log (L-IR/L-circle dot)= 12.00-12.99], in the Great Observatories ...
COMPARISON OF GNSS INDICES, IONOSONDES AND ALL-SKY IMAGERS IN MONITORING THE IONOSPHERE IN BRAZIL DURING QUIET AND DISTURBED DAYS
(Univ Federal Parana, Centro Politecnico, 2019-01-01)
Measurements from the Global Navigation Satellite System (GNSS) have become a leading data source for ionospheric studies. Different technologies are used to monitor the ionospheric layer. It is possible to carry out this ...
Relativistic effects of our galaxy's motion on circles-in-the-sky in CMB maps
(2005-06-07)
For an observer in the Hubble flow, the last scattering surface (LSS) is well approximated by a 2-sphere. If a non-trivial topology of space is detectable, then this sphere intersects some of its topological images, ...
Automatic space object detection on all-sky images from a synoptic survey synthetic telescope array
(Elsevier, 2020)
Detection, classification, and characterization of Space Objects (SOs) are important tasks in many areas of research. Detection of SOs is important in predicting collisions with debris that could become hazards for satellites ...
A new method to estimate cloud cover fraction over El Leoncito Observatory from an all-sky imager designed for upper atmosphere studies
(Univ Chicago Press, 2013-01)
A method for determining cloud cover fraction over El Leoncito Observatory (31.8°S, 69.3°W) is presented. Data from an all-sky imaging system, designed to measure nightglow originating from the mesosphere and thermosphere, ...
A Southern Sky and Galactic Plane Survey for Bright Kuiper Belt Objects
(2011)
About 2500 square degrees of sky south of declination -25 degrees and/or near the galactic plane were surveyed for bright outer solar system objects. This survey is one of the first large scale southern sky and galactic ...
