CONDITIONS: ANY CCD: FULL 13'x13'arcmin READOUT: ONE AMP GAIN INDEX: 3: Read Noise ~ 3.5 ADU = 3.5 e- FILTER SET: UBVRI ----------------------------------------------------------------------- NOTES FOR TARGET FIELDS ----------------------------------------------------------------------- Our program is to observe bright Kuiper Belt objects (KBOs) to 0.01 arcsecond precision in order to obtain very precise astrometry. Some objects can only be observed at the very beginning or end of the night. The observations are simple direct imaging mostly in the R-band. Images of the KBOs should be no more than about 10 minutes each to prevent trailing losses of the moving KBOs. All integrations either 10, 80 or 600 seconds. 15 arcsecond dithering between successive images is requested. No finder charts. R-band filter for all observations. The proper J2000 RA and Dec for each KBO for November 2009 is put below. Please observe this list on both Nov. 19 and Nov. 20 if clear. If only partially clear please try to get good observations of the high priority objects. ----------------------------------------------------------------------- NOTES FOR CALIBRATION FIELDS ----------------------------------------------------------------------- No standards are needed. Only ten biases and ten R-filter dome flats are needed. ----------------------------------------------------------------------- OBSERVING SEQUENCE ----------------------------------------------------------------------- TARGET KBO (55636) 2002TX300 PRIORITY 2 COORDINATES 00 34 07.0 +27 58 00 (J2000) FINDER CHART none AIRMASS best available FILTER(S) R INTEGRATION(S) 5 exposures of 600 seconds TOTAL TIME 60 minutes TARGET KBO Eris PRIORITY 2 COORDINATES 01 38 10.0 -04 38 00 (J2000) FINDER CHART none AIRMASS best available FILTER(S) R INTEGRATION(S) 5 exposures of 600 seconds TOTAL TIME 60 minutes TARGET KBO Sedna PRIORITY 2 COORDINATES 03 27 47.0 +06 25 10 (J2000) FINDER CHART none AIRMASS best available FILTER(S) R INTEGRATION(S) 7 exposures of 600 seconds TOTAL TIME 80 minutes TARGET KBO (55638) 2002VE95 PRIORITY 1 COORDINATES 04 34 04.0 +09 06 10 (J2000) FINDER CHART none AIRMASS best available FILTER(S) R INTEGRATION(S) 6 exposures of 600 seconds TOTAL TIME 70 minutes TARGET Starfield 55638_20101103 PRIORITY 1 COORDINATES 04 46 56.0 +09 07 20 (J2000) FINDER CHART none AIRMASS best available FILTER(S) R INTEGRATION(S) 10 exposures of 80 seconds TOTAL TIME 30 minutes TARGET KBO Orcus PRIORITY 2 COORDINATES 09 49 33.0 -06 20 10 (J2000) FINDER CHART none AIRMASS best available FILTER(S) R INTEGRATION(S) 5 exposures of 600 seconds TOTAL TIME 70 minutes TARGET KBO Varuna PRIORITY 1 COORDINATES 07 36 21.0 +25 46 00 (J2000) FINDER CHART none AIRMASS best available FILTER(S) R INTEGRATION(S) 7 exposures of 600 seconds TOTAL TIME 80 minutes TARGET Starfield Varuna_20100219 PRIORITY 1 COORDINATES 07 29 22.0 +26 07 20 (J2000) FINDER CHART none AIRMASS best available FILTER(S) R INTEGRATION(S) 10 exposures of 10 seconds TOTAL TIME 20 minutes
