[Tiziano Olivetti : Soiano del Lago Italy]

With the 150mm cassegrain at 300x. 
I profit of a one hour of clouds hole with a clear sky for this observation.
The view is horizontally inverted.
An anomaly was captured at 21h10UT on the limb above Eridania in spite of
the agitated images, Eridania was set just, therefore not seen being just
behind the limb.
The limb anomaly disappeared at around 21H30UT.
Is it a protusion?
If somebody can confirm the event with a similar observation this could be
welcome.
