On October 19, the third European 12-m antenna was transported from the Operations Support Facility (OSF) at 2900 m asl to the Array Operations Site (AOS) at 5000 m asl. This brought the number of antennas at the AOS to 22.
The picture shows 22 antennas at the AOS. As the second Japanese 7-m antenna is behind the Japanese 12-m antenna on the far right, you might be able to count only to 21.
