00:30The shape of the nucleus is also difficult to pin down because generally we're not resolving
00:45it in our observations. It's obscured by the dust and especially it's obscured by the reflected
00:51sunlight off of the dust in the inner part of the coma. But what observers from the ground
00:57have been able to do is observe the brightness of the center of the comet over time to see
01:03if there's a modulation of that brightness that would be an indication of rotation. And
01:09it's very difficult to discern. So what it's looking like so far is that there's not a big,
01:17the shape of the nucleus is not very far from being round. It doesn't seem to be a big,
01:22but at least we're not seeing signatures of a very elongated object yet.
