Here is the image posted, taken from the JAXA web page, at 4:19 UTC. Likely taken as much as 30 to 40 minutes prior to Minerva release.

Gyroscope issues detected, but not relevant because rovers can communicate in any orientation.
Sunrise should be around 10:00 UTC, but when sun will actually hit panels depends on terrain.
Telemetries reveal at least one picture has been taken but not yet transmitted.
Data rate is 32 kbps.

Sunrise over rovers should have happened since a couple of hours now, but who knows where they are w.r.t H2?
Deployment happened at 04:35 UTC, which means 16 minutes after this image was taken:
http://www.hayabusa2.jaxa.jp/en/galleries/...01809210419.jpg

UTC 04:17: H2 is 100 meters away from surface.
UTC 04:35 Rover deployment , H2 is 55 meters away.

So we can assume taht the image was taken (at 04:19) when H2 was around 90 meters from surface. Hence landing site should be not so far from where H2 shadow appears in the image.
Is anybody able to draw that point over one of the 3d models available around?
BTW, is there any hires 3d model available now? First models were very raw.

So, a nice build-up, a bunch of tweets right up to separation, and then... nothing?

Huh? Am I missing something? Is there a secret forum or thread somewhere in here where the current status of the mission is actually being discussed?

Last I heard they lost contact with them and think it's because they're on the surface of the asteroid on the other side. Though they should have experienced a fully "day" so far now... at least a couple times.
