Site Weather History
We feel very confident our skies at Riverland Dingo Observatory Telescope Farm are the clearest in Australia. To back up our statement we have decided to record the clear nights per month and publish them on our web page.
NO OTHER TELESCOPE HOSTING FACILITY DOES THIS!
Generally the south of Australia has endless waves of cold fronts, with northern Australia bombarded with tropical weather patterns year round. Our site is located between these Southern and Northern Australian weather patterns placing us in a better position of relative stability. Also we are located in an arid desert climate which general means days are hot with the nights being very cold (except for in the middle of summer where temperate at night can hover around 28C / 80F due to extended heat waves. Sight normally ranges from 1.5" to 2.8" FWHM with best being around 1" FWHM and the maximum being around 4.5 FWHM.
