We have measured spatial and temporal variability in the y-band sky brightness over the course of four nights above Cerro Tololo near Cerro Pachon, Chile, the planned site for the Large Synoptic Survey Telescope (LSST). Our wide-angle camera lens provided a 41° field of view and a 145'' pixel scale. We minimized potential system throughput differences by deploying a deep-depletion CCD and a filter that matches the proposed LSST y3 band (970 -1030 nm). Images of the sky exhibited coherent wave… Expand

A daytime measurement of the lunar contribution to the night sky brightness in LSST’s ugrizy bands–initial results
We report measurements from which we determine the spatial structure of the lunar contribution to night sky brightness, taken at the LSST site on Cerro Pachon in Chile. We use an array of sixExpand

Spectral calibration for the Maunakea Spectroscopic Explorer: challenges and solutions
The Maunakea Spectroscopic Explorer (MSE) will each year obtain millions of spectra in the optical to nearinfrared, at low (R ≃ 2; 500) to high (R ≃ 40; 000) spectral resolution by observing >3000Expand
An All Sky Transmission Monitor: ASTMON
We present here the All Sky Transmission MONitor (ASTMON), designed to perform a continuous monitoring of the surface brightness of the complete night-sky in several bands. The data acquired are usedExpand
Foreground and sensitivity analysis for broad band (2D) 21cm--Ly-alpha and 21cm--H-alpha correlation experiments probing the Epoch of Reionization
A detection of the predicted anticorrelation between 21cm and either Ly-alpha or H-alpha from the Epoch of Reionization (EOR) would be a powerful probe of the first galaxies. While 3D intensity mapsExpand
