Abstract

(abridged) Beginning in 2002, HST and Chandra monitoring of the M87 jet detected a dramatic flare in knot HST-1 located ~0.8" from the nucleus. Its brightness increased seventy-fold in the optical band before peaking in 2005; the X-rays show a similarly dramatic outburst. To our knowledge this is the first incidence of an optical or X-ray outburst from a jet region which is spatially distinct from the core source -- this presents an unprecedented opportunity to study the processes responsible for non-thermal variability and the X-ray emission. We propose five epochs of HST/ACS flux monitoring during Cycle 15, as well as seven epochs of Chandra/ACIS observation (5ksec each). At two of the HST/ACS epochs we also gather spectral information and map the magnetic field structure.
