Dear colleagues,
for all those who could not see the partial solar eclipse on January 4th 
it can be found as a quick look of ionospheric effects at the  SWACI website
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.
