Narrative:
While descending from FL190 on an IFR flight I busted the 11000 ft altitude I was cleared to. There was an overcast layer ahead of me that FSS had PIREPS for icing. I was thinking about getting down below the bases before we arrived to the area of overcast clouds. I was in VMC with good visibility (10+ mi) and wasn't thinking about my clearance. I think the fact that it was VMC might have contributed to my not thinking about my clearance. Center asked me for my altitude at 10300 ft. I reported 10300 ft and correcting. 20-30 seconds later, I reported level at 11000 ft. There was no traffic conflict that I am aware of and the controller didn't give me any indication of any traffic.

Title: A C210 PLT DSNDED BELOW HIS ASSIGNED ALT. THE ARTCC RADAR CTLR ALERTED AND CORRECTED THE PLT.
Narrative: WHILE DSNDING FROM FL190 ON AN IFR FLT I BUSTED THE 11000 FT ALT I WAS CLRED TO. THERE WAS AN OVCST LAYER AHEAD OF ME THAT FSS HAD PIREPS FOR ICING. I WAS THINKING ABOUT GETTING DOWN BELOW THE BASES BEFORE WE ARRIVED TO THE AREA OF OVCST CLOUDS. I WAS IN VMC WITH GOOD VISIBILITY (10+ MI) AND WASN'T THINKING ABOUT MY CLRNC. I THINK THE FACT THAT IT WAS VMC MIGHT HAVE CONTRIBUTED TO MY NOT THINKING ABOUT MY CLRNC. CTR ASKED ME FOR MY ALT AT 10300 FT. I RPTED 10300 FT AND CORRECTING. 20-30 SECONDS LATER, I RPTED LEVEL AT 11000 FT. THERE WAS NO TFC CONFLICT THAT I AM AWARE OF AND THE CTLR DIDN'T GIVE ME ANY INDICATION OF ANY TFC.
