Philae is in a sort of pit, being overshadowed by a cliff. Solid wall less than a meter away.

DLR now explaining that it was clear, almost immediately after initial touchdown, that there was something wrong. Philae was moving again.

Quickly confirmed that a bounce had taken place.

After 2 hours all movement stopped.

30 minutes after final stop normal LOS took place.

AOS this morning was normal.

Lander is performing normally, from a systems point of view.

Still determining whether lander is not at too great an angle relative to the surface.

Question about how the lander will cope with reduced solar exposure.
"Less solar power than we planned for- 1.5hrs rather than 6 or 7"
"Calculating now what this means for the near future. Not a situation we were hoping for."

Less solar power being received than previous planned.

Planned was 6 to 8 hours of sunlight. Now down to only 1.5 hours of sunlight per 12 hour rotation.

Batteries working OK. Exact energy budget under review.
