“…A completely new experiment was also conceived in collaboration with IASF-Bologna, University of Bologna and SAO (Russia). TORTORA [11,12] is a separated telescope hosted in parallel to REM, mechanically fixed in the same mount (see Figure 1). The aim was to study short stochastic optical flares of different objects (GRBs, SNs, etc.)…”

We present the result of a year-long effort to think, design, build, realize, and manage the robotic, autonomous REM observatory, placed since June 2003 on the cerro La Silla, ESO Chile. The various aspects of the management and control are here surveyed, with the nice ideas and the wrong dead ends we encountered under way. Now REM is offered to the international astronomical community, a real, schedulable telescope, automatic for the People.

“…Real-time data processing, based on fast differential imaging and interlinking of events on several consecutive frames [4,18], will allow us to detect both fast flashes (with durations longer than 0.3 s) and rapidly moving satellites (with velocities up to half degree per second), as well as meteors (even meteors appearing on a single frame, as they are selected on the basis of their elongated shape), and roughly classify them on the fly. For transients, the light curve and coordinates will be stored, while for satellites -the trajectories will also be stored for further processing by more sophisticated methods in day time.…”

Abstract. Here we briefly summarize our long-term experience of constructing and operating wide-field monitoring cameras with sub-second temporal resolution to look for optical components of GRBs, fast-moving satellites and meteors. The general hardware requirements for these systems are discussed, along with algorithms for real-time detection and classification of various kinds of short optical transients. We also give a status report on the next generation, the MegaTORTORA multi-objective and transforming monitoring system, whose 6-channel (Mini-MegaTORTORA-Spain) and 9-channel prototypes (Mini-MegaTORTORA-Kazan) we have been building at SAO RAS. This system combines a wide field of view with subsecond temporal resolution in monitoring regime, and is able, within fractions of a second, to reconfigure itself to follow-up mode, which has better sensitivity and simultaneously provides multi-color and polarimetric information on detected transients.

“…30,31 It is based on a fast image subtraction taking into account the statistical properties of each pixel in time domain. Robust transient detection algorithm is typically able to detect and classify the transient in a 0.4 seconds (3 consecutive frames) since its onset.…”

We present the design of a MegaTORTORA telescope (and its prototype, mini-MegaTORTORA, presently in construction at Special Astrophysical Observatory) -modular, multi-purpose, scalable grid of optical cameras based on commercially available objectives and fast CCDs, able to operate with sub-second temporal resolution in both wide-field monitoring regime with all objectives observing different regions of the sky as well as in narrow-field follow-up mode with co-aligned channels and installed color and polarimetric filters for detailed investigation of selected objects, and to change the regime of operation on a sub-second time scale.
