Solar panels power production: 4 out of 6 are producing.

Internal lander temperature at sunrise is already -35°C (minimum operating temperature is -45°C)
Sunrise Not enough power Sunset
Typical comet day
Needed for drill and ovens (analysis)

Possible Philae location.Closer flybies needed for confirmation. Rosetta currently at 250 km from comet due to dusty environment.Closest approach in past months was 8 km.
Planned landing site: northern emisphere, 9 hours of light out of 12.4.
Actual landing site: southern emisphere during winter, hence mostly in shadow until june 2015.
Energy increment due to 22° lander rotation on 14/nov/2014: +20%
Philae wakes up (jun 13): +320%
Perihelion (shortest distance from Sun): +480%
Solstice (longest daytime): +210%
Equinox (day starts being longer than night): +50%
