I ran into this brief article that mentions that Monday night, flights between Australia and Indonesia were disrupted by an ash plume from an unknown volcano (well, unknown to the Virgin Blue spokesperson quoted in the article). Checking out the Darwin VAAC, it appears that the volcano in question is, in fact, Bromo in the Tengger Caldera. Bromo has been rumbling for most of the late fall, but had quieted as of late, but is still at alert status 3. However, the current ash advisory for Bromo has ash as high as FL200 (6 km / 20,000 feet). Sounds like the airlines don't really know if flights will be able to resume in the near future, but it does appear that Bromo isn't quite done for the season.
More details as they arrive ... and feel free to post any information you find.
