GRBs observed by SWIFT or/and other satellites in 2008

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

In LCO 10 s exposures of a 21°x 21° field were taken by two cameras.

Twice a night the whole sky was 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%.
