<div><font color="navy" face="Arial" size="2"><span
style="font-size: 10pt;">Due
to the reduced solar illumination the ionization develops delayed over
Europe indicated by the negative TEC deviation from the corresponding
27days median. In addition to this reduction
the eclipse caused probably a gravity wave which is clearly indicated
by the time variation of the critical frequency and the equivalent slab
thickness over the Juliusruh ionosonde station. </span></font></div>
