just a heads up for Europa to conjunct (or is it transit?) with Jupiter and will cast a shadow on the Great Red Spot on the 10th of April between approx 1630-1900 aest. it will be spot on at 1743 aest according to mobile observatory from a se qld location.
hopefully the suns low enough to see this,(and its not cloudy but the forecast looks bad). I have no idea if its rare or anything but since Jupiter is getting lower and lower it might be something to see before it disappears.
ps - hope someone can get some pics
