VERITAS observations of very high energy emission from B2 1215+30 — •Heike Prokoph — DESY, Platanenallee 6, D-15738 Zeuthen

VERITAS is an array of four imaging atmospheric Cherenkov telescopes located in southern Arizona sensitive to gamma rays in the very high energy range (VHE; E>100GeV). The investigation of gamma-ray emission from blazars is one of the VERITAS collaboration’s key science projects.

This contribution investigates the VHE emission from the low-frequency-peaked BL Lacertae object B2 1215+30. It was first reported as a VHE source by the MAGIC collaboration in early 2011 during a flare that lasted four nights. Based on VERITAS observations performed from December 2008 to June 2011 I will report on the detection and spectral analysis of B2 1215+30 as well as its long term variability.
