From TORTORA to MegaTORTORA—Results and Prospects of Search for Fast Optical Transients
To study short stochastic optical flares of different objects (GRBs, SNs, etc.) of unknown localizations as well as NEOs it is necessary to monitor large regions of sky with high-time resolution. We developed a system consisting of widefield camera with field of view of 400–600 sq.deg. which uses TV...

| description | To study short stochastic optical flares of different objects (GRBs, SNs, etc.) of
unknown localizations as well as NEOs it is necessary to monitor large regions
of sky with high-time resolution. We developed a system consisting of widefield
camera with field of view of 400–600 sq.deg. which uses TV-CCD with
0.13 s temporal resolution to record and classify optical transients, and a fast
robotic telescope aimed to perform their spectroscopic and photometric investigation
just after detection. Such two-telescope complex, combining wide-field
camera TORTORA and robotic telescope REM, operated from May 2006 at
La Silla ESO observatory. Some results of its operation, including first high
time resolution study of optical transient accompanying GRB and discovery
of its fine time structure, are presented. Also, prospects for improving the
efficiency of such observations are given, and a project of a next generation
wide field monitoring system, the MegaTORTORA, is described. |
