                         two candidate gravitational-wave (GW) transient events recorded by 
                         LIGO and Virgo in their 20092010 science run. The events were 
                         selected with low latency by the network of GW detectors (within 
                         less than 10 minutes) and their candidate sky locations were 
                         observed by the Swift observatory (within 12 hr). Image transient 
                         detection was used to analyze the collected electromagnetic data, 
                         which were found to be consistent with background. Off-line 
                         analysis of the GWdata alone has also established that the 
                         selected GW events show no evidence of an astrophysical origin; 
                         one of them is consistent with background and the other one was a 
                         test, part of a blind injection challenge.With this work we 
                         demonstrate the feasibility of rapid follow-ups of GW transients 
                         and establish the sensitivity improvement joint electromagnetic 
                         and GW observations could bring. This is a first step toward an 
                         electromagnetic follow-up program in the regime of routine 
                         detections with the advanced GW instruments expected within this 
                         decade. In that regime, multi-wavelength observations will play a 
                         significant role in completing the astrophysical identification of 
                         GW sources. We present the methods and results from this first 
                         combined analysis and discuss its implications in terms of 
                         sensitivity for the present and future instruments.",
