    7 The Burst Alarm System is installed and working since last summer
    8 in La Palma. The duty of the Burst Alarm System
    9 is to perform a full-time survey of the {\it GRB Coordinates Network} (\g)~\cite{GCN} alerts. Different satellite experiments perform GRB monitoring
    10 in their wide FOV and send immediately the coordinates of the GRBs to the \g network.
    11 The network send the alerts to registered users and allows other satellites as well as
    12 ground based observatories to observe the GRBs and their afterglows at different wavelengths.
    13 The Burst Alarm System is composed by a core program -
    14 which acts in two ways: on the
    15 one hand it manages the monitoring of the \g, on the other it manages
    16 the communication with the Central Control (CC). Then it also manages
    17 three communication channels to notice the shifters
    18 about an alert situation. The program is called {\it gspot} (Gamma
    19 Sources Pointing Trigger). It is a C based daemon running 24

    3633The format of the data distributed through the \g differ between the individual satellites
    37 and the kind of package. There are three satellites participating in the GRB survey:
    38 HETE-2~\cite{HETE}, INTEGRAL~\cite{INTEGRAL} and SWIFT~\cite{SWIFT}. All are sending alerts which include the
    39 UTC, coordinates (not always), error on coordinates
     34and the kind of package. Currently, three satellites participate in the GRB survey:
     35HETE-2~\cite{HETE}, INTEGRAL~\cite{INTEGRAL} and SWIFT~\cite{SWIFT}.
     36The alerts include the UTC, the GRB coordinates (not always), error on coordinates
    4037(not always) and intensity (photon counts) of the burst.
    4138The first notices from HETE-2 and INTEGRAL usually do not include the coordinates.
    42 In few cases only coordinates are distributed in more refined notices.
     39In few cases only coordinates are distributed in refined notices.
    4340The \sw alerts are predicted to arrive with coordinates between 30-80 sec after the onset of the burst.
    4441The error on the coordinates from the BAT detector will be 4 arcmin which is smaller than the size of one
