 to point and observe GRBs.
 
 \begin{itemize}
 \item {\bf Yellow Alarm strategy}
-First of all the strategy to follow in case of a yellow
-alarm, i.e. in case of a not observable GRB, is not defined yet.
+The strategy to follow a {\bf Yellow Alarm} is not defined yet.
 In such a case the CC does not undertake any steps,
 except confirming the alarm notice to the Burst Monitor. We do not
 calculate if and when the GRB will become observable.
 It would make sense to check if during the period of 5 hours we could point to the burst.
-Then the Alarm System would change to {\bf Red Alarm State} 
+Then, the Alarm System would change to the {\bf Red Alarm State}

-in alarm state. The status of the system now is that {\it gspot}

+Such a situation can occur when the CC is switched off and thus 
+cannot receive the alert and if more than one alert happens

 \begin{itemize}
-\item having been noticed to the CC;
+\item having been noticed by the CC;
 \item the canonical 5 hours.
 \end{itemize}
 
-If more than one alert is present in the list then the program
