I am seeking to obtain V, Rc, and Ic data on this blazar with the Coker30 telescope for the purpose of contributing to the international multifrequency campaign of Fermi, GASP, and VERITAS (TeV collaboration), among others. I need 360 second images (e.g. 3-two minute exposures), more or less, in each of the three filters about once a week throughout the spring and summer. (The comparison stars are in the image frames.) Such observations can be considered as low priority in the sense that they can be inserted as time permits.
I use MIRA Pro 7 UE software package to do the reduction as CCD aperture photometry. These data, together with others participating in this campaign, would be published in the standard astronomical journals in collaboration with the high energy colleagues involved in this campaign. Naturally, the AAVSO would be gratefully acknowledged in any publication.
