Observing Conditions at Mount Graham: Vatican Advanced Technology Telescope UBVR Sky Surface Brightness and Seeing Measurements from 1999 through 2003
We present measurements of sky surface brightness and seeing on Mount Graham, obtained at the Vatican Advanced Technology Telescope (VATT) during 16 observing runs between 1999 April and 2003 December. We show that the sky surface brightness is significantly darker during photometric conditions and can be highly variable over the course of a single observing run, as well as from one run to the ...
متن کاملMultispectral analysis of Asteroid 3 Juno taken with the 100-inch telescope at Mount Wilson Observatory
High-resolution multispectral images of main-belt asteroid 3 Juno were taken at visible and near-IR wavelengths with the 100-inch telescope at Mount Wilson Observatory equipped with an adaptive optics system. The images show spectral features that may represent a large relatively recent impact that deeply excavated the coarse-grained olivine–pyroxene-rich crust of the asteroid. © 2003 Elsevier ...
متن کاملRem – Rapid Eye Mount. a Fast Slewing Robotized Infrared Telescope
The main goal of the REM project is the observation of prompt afterglow of Gamma–Ray Burst (GRB) events. Such observations at Near InfraRed (NIR) wavelengths are even very promising, since they allow to monitor high–z Ly-α absorbed bursts as well as events occurring in dusty star–forming regions. In addition to GRB science, a large amount of time (∼ 40%) will be available for different scientif...
متن کاملInexpensive mount for a large millimeter-wavelength telescope.
A telescope mount with a single-point force support at the center of gravity of the primary mirror is proposed in order to eliminate much of the structure and cost of a large, millimeter-wavelength telescope. The single-point support gives repeatable thermal and gravitational deformation, so the surface of the primary can be controlled based on lookup tables for elevation and temperature. The n...
متن کاملTurbulence Monitoring at Mount John
In this paper we present preliminary results of a turbulence monitoring campaign at the Mount John University Observatory using a bread-board based SCIDAR (SCIntillation Detection And Ranging) system. Simultaneous SCIDAR and generalised SCIDAR data are captured and used to quantify the turbulence at the site. Initial results, including estimates of key turbulence parameters, are presented and d...
