Note that the antennas are designed such that winds of speeds greater than 29km/hr will deleteriously affect the pointing. For further information refer to Cooper et al. (1992).
There are two independent monitoring systems to help the observer monitor the Compact Array. The Primary Monitoring (PMON) system is a hardware system that monitors critical components of the array (basically for fire, power and cryogenics failure and some weather data). The PMON rack is in the Observer's Area, and alarms are heard in the control building, and are distributed to the site houses. If you hear an alarm and are unsure about what to do, do nothing: In general, the site staff respond pretty quickly to these alarms. Consult the Duty Astronomer if you have any concerns about the PMON rack.
As well as the Hardware PMON system, there is a large amount of software monitoring the array which should help the observer be aware of array problems as they arise. These programs include ASSISTANCE, CAMON, WINDS, LOPLOT, MONICA, and others. Please leave any array monitoring programs running and heed any warnings as they come up. Again, if in doubt, consult the Duty Astronomer.
