Ultra-long GRB 091024

Author: Francisco Virgili

Abstract: I will present the data collected on ultra-long GRB 091024 by the 2-m robotic Faulkes North and Liverpool Telescopes in the context of our upcoming optical gamma-ray bursts catalog. I will broadly summarize our catalog sample and showcase ultra-long GRB 091024 as an example. This GRB shows significant optical structure in addition to its unique high-energy properties and I compare this burst to other ultra-long GRBs and comment on possible detectability with LSST.
