News from the ORCA campaign – hard work ongoing, bad weather approaching
21 November 2021 – The weather forecast does not look promising for next days. The main effort today was spent on some tuning of the equipment and preparation to next steps.

Two new detection units added to ORCA… and counting
20 November 2021 – It was night and day again. The work continues around the clock when you are at sea. The second detection unit was also deployed, connected and tested last night. After that, unfurling was performed for the two detection units. A final test was then made from the shore to check that the two units are ok even after unfurling, et… voilà: ORCA is enlarged to 8 detection units.
First day of activity at the ORCA site
19 November 2021 – The first day of activity has gone at the ORCA site. Most efforts today were aimed at getting everything well prepared for the action. The first detection unit was then deployed to the sea bottom, precisely placed on the sea floor and connected to the submarine infrastructure. The tests performed from shore confirm that the dection unit is nicely working, and it now awaits to be “unfurled” to its work configuration. Deployment of the second detection unit has been started in the evening.
Time to resume data taking in ARCA
15 September 2021 – after the recovery of two old detection units, already left disconnected after previous sea campaigns – the so-called PPM-DU (Pre-Production Model of Detection Unit), a 3-digital optical module unit used for qualification of the project in the sea as early as in 2014, and one of the first prototype full-size detection units deployed in spring 2016, the sea campaign of ARCA has been completed today.
A very busy day, offshore and onshore
13 September 2021 – Still a day packed of activities today!
Good progress, despite adverse sea condition
12 September 2021 – there has been good progress in the operation so far!
First day of deployments at the ARCA site
11 September 2021 – operations are proceeding smoothly on Handin Tide.

10 September 2021 – In the evening of September 10, five new detection units of KM3NeT, onboard the Handin Tide, will sail from Malta headed to the KM3NeT/ARCA detection site. This site is located 80 km off the coast of Capo Passero, Sicily (Italy). During a 1-week operation, the detection units will be deployed and connected to the ARCA neutrino telescope at 3,500 m depth, adding up to the six already in operation.
KM3NeT at ICRC2021
29 July 2021 – The International Cosmic Ray Conference (ICRC) has come to an end after two intense weeks.
The biannual conference organised under auspices of IUPAP, the International Union of Pure and Applied Physics. This year, the 37th edition of the conference was organised as an online version by DESY Zeuthen in Germany. The KM3NeT Collaboration participated in the conference with many contributions accepted by the International Science Committee of the conference.
Yet another virtual spring meeting
A few weeks ago, KM3NeT held its two-week long spring meeting, once again virtually, like almost all meetings nowadays.
