The 2009 – 2010 outburst (data from the Faulkes Telescopes, Swift BAT, RXTE ASM and WHT. These data have appeared in ATel #2775 and in the MNRAS paper, “A late jet rebrightening revealed from multi-wavelength monitoring of the black hole candidate XTE J1752-223” by Russell et al. here.

Finding charts (all north = top, east = left):

Faulkes i’-band on 2010-07-15 (260 sec, seeing = 0.9″):
40 x 60 arcsec FOV; red circle = 0.31″ UVOT error circle from Curran et al. 2010.

The faint star 0.8″ to the north has magnitudes V > 20.3; R = 19.7 +- 0.1; i’ = 18.4 +- 0.2

2MASS H-band

40 x 60 arcsec FOV; red circle = 0.31″ UVOT error circle from Curran et al. 2010.

WHT LIRIS images: H-band (left; 240 sec) and Ks-band (right; 360 sec) on 2010-07-01 (seeing = 0.6″ – 0.8″):
20 x 20 arcsec FOV; counterpart marked

XTE J1752-223 had magnitudes H = 15.6 +- 0.1; Ks = 15.2 +- 0.1 on this date (fade towards quiescence).

The faint star 0.8″ to the north has magnitudes H = 15.5 +- 0.1; Ks = 15.2 +- 0.1
