To reserve accommodation at any ATNF site, visitors must fill in the www-based ATNF Reservation Form. Observers are encouraged to spend a few days at the ATNF Sydney headquarters before and/or after their observations. You will need to discuss data analysis with ATNF staff, and many observers analyse their data either at the ATNF in Sydney or at the Observatory. First time observers should arrive at the observatory at least one day before observations start to familiarise themselves with the control room and ask for a tour.
