4U1735-44 = V926 Sco Chandra campaign on May 14 From Dr. Vrtilek: Date: Thu, 04 May 2000 13:56:52 -0400 From: Saku Vrtilek <saku@head-cfa.harvard.edu> Subject: [vsnet-obs 27540] (No Subject in original) Dear Observers, We have Chandra observations of 4U1735-44 scheduled on May 14. This is a bursting source whose optical companion (V926 Sco) has a v-mag of 17.5. It as an Av of 0.8 and an orbital period of roughly 4 hrs. If anyone is able to obtain either optical photometry or spectroscopy of this source at or near the Chandra observations they will be of interest (especially if we are lucky enough to capture a burst!)
