On 26th of June, I observed a really magnificent cumulonimbus cloud with some impressive mammatus! The beginning of this display was a humble one, but it developed into a really good show! The cloud was evolving quickly, and it was possible to see the mammatus to grow and change shape! You just don’t see clouds like this every day!
