The forecast satellite loops - I presume you were viewing
BoM ACCESS-G model forecast loops you weren't meant to see? Pity you lost the access if you found them good!
Kevin, they were forecast synthetic satellite images, giving a modelled idea of cloud cover, which is really handy for planning an observation session. ACCESS-G is the Bureau's global weather forecasting model. You can see similar cloud cover images from the GFS forecast model at this link (BSCH)
e.g. 10pm Saturday. The new BoM satellite viewer shows real satellite images from earlier in the day, also very handy for giving a rough idea if clouds are headed your way a few hours before an observing session.
