🛥️ Welcome ORCA33! 🌞
We had a new successful sea campaign:
1) We reconnected 4 lines previously installed and tested on node 1 to the newly deployed node 2
2) We deployed and connected 5 new lines to node 2
Big thanks to everyone involved for this great step!

We are very proud of our PhD student Nadja Lessing from @vegaific.bsky.social! She won the @europhysicssociety.bsky.social poster prize at the Majorana School held in Modica (Sicily, Italy)!
👏👏👏
On her poster she shows how KM3neT can search for quantum decoherence
Have a look and get inspired!
