White Foamy dots

[MikeRoberts]

White foamy dots floating in Secondary Fermentor. It has only been in there for 8 hours. Yeast rafts? Mold? Should I worry? Just not sure. It's a Roggenbier made with hefeweizen yeast.

Could be small groups of air bubbles rising from the bottom and haven't popped

Doesn't look like a problem. Come ack when you have a film across the surface and large bubbles in it.
