TL;DR: The Rapid Telescopes for Optical Response (RAPTOR) experiment as discussed by the authors is a spatially distributed system of autonomous robotic telescopes that is designed to monitor the sky for optical transients.

TL;DR: RAPid Telescopes for Optical Response is an example of a distributed network of telescopes that performs more efficiently in synchronous operation than as individual instruments.

TL;DR: The RAPTOR project aims to construct a new type of system for discovery in optical astronomy---one that explores the time domain by "mining the sky in real time" by recognizing important variations in known sources.

TL;DR: In this article, the RAPTOR project is described as a pioneering close-loop system combining real-time transient detection with rapid follow-up, which is able to identify and localize an optical transient within seconds after the observation.

Abstract: We describe the design and operation of a small, transportable, robotic observatory that has been developed at Los Alamos National Laboratory. This small observatory, called RQD2 (Raptor-Q Design 2), is the prototype for nodes in a global network capable of continuous persistent monitoring of the night sky. The observatory employs five wide-field imagers that altogether view about 90% of the sky above 12 degrees elevation with a sensitivity of R=10 magnitude in 10 seconds. Operating robotically, the RQD2 system acquires a nearly full-sky image every 20 seconds, taking more than 10,000 individual images per night. It also runs real-time astrometric and photometric pipelines that provide both a capability to autonomously search for bright astronomical transients and monitor the variability of optical extinction across the full sky. The first RQD2 observatory began operation in March 2009 and is currently operating at the Fenton Hill site located near Los Alamos, NM.We present a detailed description of the RQD2 system and the data taken during the first several months of operation.
