CubeBug-1 was OFF on first pass this morning. But currently monitoring 0159utc pass and it is back ON.

LU1CGB just had a good pass and was able to decode, here’s what he saw:

As you can see the battey is lower than usual (still in a safe range), the low power counter is at 2 (first time we actually see it), the satellite is in the shadow, and it is spinning quite fast.
This is very good information to try to understand what’s going on. Thought we are still not sure why, the CubBug-1 is sometimes using more energy than what it collects from the Sun, until it powers itself off to protect the battery berore it gets dangerously low.
