Hope this hasn't already been covered, tried searching with no luck.

I bottled my first batch yesterday. I noticed during the first few bottles that as the bottle filled up it was creating several bubbles, even a slight layer of foam by the time the bottle filled up. Thought maybe it was because the bottling bucket was still full and maybe the pressure on the beer through the line was causing it. I tried closing the spigot a little more which stopped the foaming in the bottle, but I noticed SEVERAL very tiny bubbles in the line leading to the bottling wand. At one point there was a little cyclone forming right at the bottom of the spigot leading into the hose.

Was little concerned that this was blowing my beer full of oxygen.
 
Don't worry,Have a homebrew. I assume it wasn't a BIG beer for your first? As long you are not aging it for extended periods of time, you will not even notice it. I drank my first batch within a month of bottling.
 
Most likely what your seeing is some residual dissolved CO2 coming out of solution as you siphon. A certain amount of CO2 is dissolved into the beer during fermentation and if left alone will eventually gas off. Sometimes you can even see this happen if you agitate the beer by moving it, or if the beer warms up a few degrees, being that CO2 is less soluble at warmer temperatures. This can even move the air-lock making you think that the beer is still fermenting after it is quite done. I've seen bubbles in my bottling lines before too. Don't worry about oxygenation though, its CO2, and it won't hurt anything.
