GRBs observed by SWIFT or/and other satellites in 2011

The “Pi of the Sky” apparatuses continuously monitor the SWIFT satellite Field of View.

In INTA 10 s exposures of a 21°x 21° field are taken by 16 cameras. In SPdA 10 s exposures of a 21°x 21° field are taken by two cameras.

Twice a night the whole sky is scanned.

Targets of GCN alerts are also followed automatically.

In a table below there are alerts, which were caused by GRB with probability greater than 50%.
