$\begin{figure} \par\includegraphics[width=8.2cm,clip]{0292fig1.eps} \end{figure}$ Figure 1: Comparison of activity of underdense echoes recorded within 2000-2002. The year 2001 did not display any activity of underdense echoes at all. The important time instants of maximum activity are marked by arrows accompanied by the day in November and time instant in UT.

Crosses represent the group of $T \! \geq \! 0.4$ s, asterisks mark the second one of $T \! \geq \! 1.0$ s, full triangles indicate $T \! \geq \! 10.0$ s. The important and interesting peaks are listed in Table 2.

The data between 10h00m and 10h30m had to be excluded from data processing because of the very bad quality of the film within this interval.
