Bubbles in AC Sight Glass

My car is a '95 E300 series and came with Freon-134.

The ambient temperature here (Montreal Canada) is now around 32F. I happen to look at the Air Conditioning sight glass while the AC compressor was running and noticed lots of bubbles.

Does that mean that I may be low on Freon, or are the bubbles due to the low ambient temperatures?
