I suppose you could update this thread with this latest interloper,
2011 CQ1/ Feb 4 /0.03 LD/ 32.1/ 2 m (info from spaceweather.com) Okay it's only little and was "known", except that it came closer than thought,
spaceweather.com...
In that day link however it is still described as a metre wide, and not two metres. Another close one will be in June, 2009 BD/ Jun 2/ 0.9 LD/ 28.3/
9 m . It is most likely that new dicoveries will occur for in between times and later during the period up to June.
