Today our pre-dawn sky had some faint NLC again - and as my observer colleagues has reported yesterday evening the situation was the same. We have a big amount of African dust in our sky now which must have decreased the NLC's brightness a lot, but still it was visible.
What I really don't understand in this sequence of almost each night observations in Hungary is the arrival of the CME on 16th June: it should have been decomposed all the water in the mesosphere - but nothing like this happened. Or is there an extra water source somewhere? This season is a mystery for me up to now...
