BOOTES provides an automated real time observing response to the detection of Gamma Ray Bursts GRBs. Error box size depending, it uses wide ﬁeld cameras (WFC), ultra wide field cameras (UWFC) and narrow field cameras (NFC) attached to small robotic telescopes or the telescopes themselves.
To study GRBs it is of the utmost importance to perform prompt optical follow up observations, to detect longer wavelength transient emission associated to them. BOOTES can perform such follow ups. Its scientiﬁc objectives include:
• Simultaneous and quasi simultaneous observations of GRB error boxes.
• Detection of optical ﬂashes of cosmic origin.
• Sky monitoring in the I, R1 & V bands.
• Monitoring of different types of objects in search of recurrent transient optical emission.
BOOTES is part, within the framework of a Spanish-Czech collaboration, of a wide ongoing effort to prepare for the ESA’s satellite INTEGRAL. The project has been now performing rapid follow up observations of events detected by BATSE, BeppoSAX, RossiXTE and the IPN, for two years. Results include:
• Predetection images: they set up upper limits for any possible precursors.
• Quasi simultaneous images: i.e. GRB 000313 as shown in the picture at the right.
