The multiwavelength campaign is looking at selected blazars in several different electromagnetic bands in order to ultimately determine if there is any time correlation between the different bands for a given source. The blazars that have been selected are Markarian 421, Markarian 501, 1ES 1959+650, 1ES 1218+304, 1ES 2344+514, and H1426+428. These six blazars were chosen because of their location in the Northern Hemisphere, as well as the fact that they are all classified as High frequency peaked BL Lacerate objects (HBLs). HBLs are neutrino point source candidates. These blazars are being observed in the optical by the WIYN 0.9m telescope at Kitt Peak. They are being observed in the TeV range by Whipple. There is X-ray data on the blazars from RXTE and from SWIFT. There is also neutrino data from these blazars from IceCube. I am mostly dealing with optical data in the B,V, and R filters, and the following pages deal primarily with the optical data.
