Alien Anomalies

Sorry, but I am in a strange mood today.

SOHO realtime images 

latest sun SOHO page

There are two 'things on this image LASCO C3 27th June 2011 03:30 which are moving.

Now... these could be 
a) bodies between the camera and the sun moving in a normal way (in which case we would have a near earth object warning if it is <1AU)
b) a radiation particle
c) something further taway than the sun moving extremely quickly.

I guess b) is the most likely but how do you tell?
Maybe this is another one of those "moving spacecraft, stationery planets" things which I dont understand. Like Pooh Bear, I dont have much between my ears.
