Introduction

BOOTES-5 is the fifth robotic observatory of the international network of robotic telescopes BOOTES (Burst Observer and Optical Transient Exploring System). It was dedicated on November 26, 2015. Its main scientific objective is the observation and monitoring of the optic counterparts of gamma ray bursts as quickly as possible once they have been detected from space or other ground based observatories. BOOTES-5 was named Javier Gorosabel Telescope (JGT) after Spanish astronomer Javier Gorosabel Urkia. The BOOTES-5 project is a collaboration between the Institute of Astronomy of the National Autonomous University of Mexico (UNAM), the Institute of Astrophysics of Andalusia (IAA), Spain, and the Sungkyunkwan University (SKKU) in South Korea.

Telescope

BOOTES-5 uses a dedicated 0.60 m f/8 Ritchey-Chretien telescope located at San Pedro Martir National Astronomical Observatory, Baja California, Mexico (Latitude 31° 02' 39" N, Longitude 115° 27' 49" W, Elevation 2860 m). The telescope has an ASTELCO NTM-500 mount with a maximum slewing speed of 20 degrees per second. The optical tube is made of carbon fiber to minimize the moment of inertia to reach it maximum slewing speed and to reduce the focus changes for thermal expansion. It operates in an open air dome.
