Abstract: We motivate searches for gravitational waves from transient blazar flares with emphasis on PKS 2155-304. PKS 2155-304 is a blazar with redshift approximately equal to 0.12. On July 28 2006, the H.E.S.S. atmospheric Cherenkov telescopes detected an outburst of TeV gamma rays from this object lasting approximately two hours with total isotropic equivalent energy released in TeV gamma rays (without accounting for attenuation with infrared photons) approximately $10ˆ{45}$ ergs. During this period, the two LIGO detectors at Hanford and GEO were running and collecting science mode data. We propose to look for gravitational waves during this gamma-ray outburst with the RIDGE network analysis pipeline. Simulated detector noise is used to study the performance achievable by RIDGE in measuring possible gravitational wave signals associated with this event.
