Now, most of the time those of us who are astronomers have a gaze fixed skyward, but if you were anywhere in the top end of Australia or in the Banda sea region in the early hours of Sunday morning (12:10am CST ) the 25th of October your concerns would have been much more earthly.
An earthquake in the Banda sea at magnitude 6.9 saw tremors, that my estimate puts between Magnitude 4 and 4.5 were felt by all (who did not sleep through it !)
I would love to hear your report of the tremor, in the comments below.

PS: I have done a science show segment on the quake that I will post up here shortly ……
