Abstract

We report the detection of a statistically significant flare-like event in the Mg ii λ2800 emission line of 3C 454.3 during the outburst of autumn 2010. The highest levels of emission line flux recorded over the monitoring period (2008–2011) coincide with a superluminal jet component traversing thro...
