ALMA hosts guided visits on Monday, Wednesday, Thursday and Friday for groups from schools, universities, institutes and related scientific organizations. The visits include a tour of the Operations Support Facility (OSF), the camp where ALMA personnel work and where visitors can observe the control room, laboratories, and usually an antenna in maintenance and antenna transporter. For safety reasons, operations on the Chajnantor Plateau (the Array Operations Site, or AOS, where the antennas are located) are not open to visitors, due to the location at 5,000 meters above sea level.
All visits must be coordinated at least one month in advance by providing all of the information required on the form below. Once a group receives authorization, the contact for the group will receive a confirmation email.
We can receive group of up to 40 people (including students, professors and/or parents/guardians). The visiting group must have its own means of transportation to the Observatory (OSF or the ALMA camp) located 35 kms from San Pedro de Atacama.
