Cirrus spissatus cumulonimbogenitus (orphan anvil)

Today, there was finally a powerfull enough cumulonimbus cloud heading our way. Low level clouds covered my view, soon. My friend from Brno sent me images of it right away showing some horizontal expansion of anvil. But the cloud base started to dissipitate and ended in a total desperation. Anvil was visible for the next two hours or so until it dissipitated, too. Cirrus cumulonimbogenitus, cumulonimbus virga and hints of mamma were visible, too.
