This approved proposal is triggered by a low/hard X-ray state with a radio flux density > 2 mJy; both conditions currently obtain for XTE J1118+480 (most recent VLA flux density: today at 8.5 GHz, 7 mJy). The proposal calls for four 8-hour observations (256 Mb/s), separated by three weeks between each, with the goal of catching the source at different flux density levels. The time of the first observation is not specified but should be within a week or so. NOTE that subsequent epochs may be delayed if the source moves into the high/soft X-ray state, as stated in the proposal. [This particular source has never been observed to make this transition, so this may be a moot point.] Thanks very much -- Michael Rupen & Peter Jonker ----- End Included Message -----
