Observations are under way with HST to attempt to estimate additional periods. We propose to continue this program concentrating our scarce HST resources on a single transient which exceeds 1e38 erg/s. Only uninterrupted monitoring can yield the duty cycles and long-term light curves of BHXNe (and other variables) in M31. Our GO+GTO programs will have accumulated over 800ks (ACIS+HRC) near the M31 bulge by the end of A10, and total Chandra exposure on M31 is now almost 1Msec. By continuing our monitoring program through AO12 we will reach ~950ks on the bulge and >1Msec total Chandra M31 exposure. ------------------------------------------------------------------------------------ Observations Description ------------------------ we will observe for 2 orbits 'on', and then 6 months later 2 orbits 'off', in a mode to get the max s/n for a faint point source in a crowded, bright field (=M31) Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- ------------------------------------------------------------------------------------ 12014( 6) - 22-Jun-2011 16:51:04 - [ 2] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 M-31-VISIT1 STAR, X-RAY NOVAE RA=00H42M57.0000S +/- 0.1", J2000 V = 20.0 +/- 2.0 DEC=+41D20'5.00" +/- 0.1" Reference Frame: ICRS ------------------------------------------------------------------------------------------------------------------------------------ 2 M-31-VISIT2 STAR, X-RAY NOVAE RA=00H42M49.0000S +/- 0.1", J2000 V = 20.0 +/- 2.0 DEC=+41D17'16.00" +/- 0.1" Reference Frame: ICRS Comments: Visit 1 holding position, to be updated 3 to 4 weeks before execution. ------------------------------------------------------------------------------------------------------------------------------------ 12014( 6) - 22-Jun-2011 16:51:04 - [ 3] Patterns ------------------------------------------------------------------------------------------------------------------------------------ Pattern_Number: 1 Primary_Pattern Secondary_Pattern Pattern_Type ACS-WFC-DITHER-BOX Pattern_Purpose DITHER Number_Of_Points 4 Point_Spacing 0.265 Line_Spacing 0.187 Coordinate_Frame POS-TARG Pattern_Orient 20.67 Angle_Between_Sides 69.05 Center_Pattern NO ------------------------------------------------------------------------------------------------------------------------------------ 12014( 6) - 22-Jun-2011 16:51:04 - [ 4] Visit: 01 Visit Requirements: PCS MODE FINE;
