Successful ToO triggers on the extragalactic sources with the MAGIC telescope

Abstract

The MAGIC collaboration has been performing Target of Opportunity (ToO) observations whenever alerted that known or potential very high energy gamma-ray emitting extragalactic sources were in a high flux state in the optical, X-ray band or/and in the TeV energy range. Here we report on MAGIC observations performed after such triggers, results of the analysis, and a possible optical-TeV correlation seen in the data. Detections as well as spectral and temporal characterestics of Mkn 180, PKS 2155-304, and 1ES 1011+496 are reported.
