    Gemini Studies a Plethora of Brown Dwarfs Candidates

    Figure 1. NIR Spectral type histogram of all known low-gravity dwarfs and those presented in this work. Green bars delimited by dashed lines represent the known population prior to BASS, purple bars delimited by dash-dotted lines represent known dwarfs for which low-gravity features were identified here for the first time, and orange bars delimited by solid lines represent new discoveries from BASS.

    Gemini North HBF Photo-Voltaic Array Power System Installation RFB

    As part of Gemini’s comprehensive energy savings initiative, Gemini North Telescope Facility (GN) seeks to install a 94.8 kW, net-energy metered photo-voltaic power system on the GN support building located at the Hilo Base Facility in Hilo, Hawaii. The proposed PV system consists 378 modules having a DC capacity of 260 W per module (98.28 kW DC total) and 4 decentralized inverters having a rated AC capacity of 24 kW AC per inverter (94.8 kW AC total). The system shall be configured in a 480 volt 3-phase arrangement.

    Special proposals require 2015B PIT

    In preparation for the start of 2015B, all new Fast Turnaround (FT), Director's Discretionary (DD) time, and Poor Weather (PW) proposals must use the 2015B Phase I Tool (PIT). See the PIT Version Table for more information and download links.
