\caption{\label{table4} Positions of main activity peaks recorded in
                          2002. The instants of the maxima are determined
                          with an error of 15~min. Our observations
                          corresponding to the forecast of Jenniskens
                          (\cite{jen1}), McNaught \& Asher (\cite{asmc3})
                          and Vaubaillon (\cite{vaub}) are presented in
                          bold (see Sect.~\ref{comp_2002}).}
