The "Pi of the Sky" apparatus continuously monitors the sky. Currently we scan the whole sky twice a night (20min/scan). For the rest of the time we follow the SWIFT FOV.
10 s exposures of a 21ox 21o field are taken by two
cameras simultaneously (2 x 2000-3000 images / night).
On-line analysis of the images is performed
in search for rapidly (~10 s) brightening point-like objects.
Sums of 8 frames are also analyzed (~100 s time scale).
The last column contains objects coinciding with the flash within 2 arcmin
and GRB alerts coinciding +-15 min in time.
The following events have been detected since 2006.05.20 (archival, since: 2004.09.01):
