BOOTES, the Burst Observer and Optical Transient Exploring System, is a network of astronomical observatories with sites in Southern Spain, New Zealand, China and Mexico (mostly 0.6m diameter telescope with EMCCD camera at the Cassegrain focus and a g'r'i'ZY filterset. The main goal of the network is to quickly observe transient events within few seconds/minutes of being detected by scientific satellites.

Boötes is a constellation in the northern sky, located between 0° and +60° declination, and 13 and 16 hours of right ascension on the celestial sphere. The name comes from the Greek Βοώτης, Boōtēs, meaning herdsman or plowman (literally, ox-driver; from βοῦς bous “cow”). The "ö" in the name is a diaeresis, not an umlaut, meaning that each 'o' is to be pronounced separately.
