Chandra Detection of Three Enigmatic X-ray Transients: GRS 1741.9-2853

The Chandra X-ray observatory ACIS-I observed the locations of two transient low-mass X-ray binaries, GRS 1741.9-2853 (see ATel #1005, #1006, #1008) and GRO J1744-28, and the unidentified very faint X-ray transient XMM J174457-2850.3 starting on 2007 Feb 22 at 03:29:33, for 39 ks. All three sources were detected. GRS 1741.9-2853 was detected at 17h 45m 2.34s, -28o 54' 49.9 (J2000; 0.5 uncertainty), consistent with Muno et al.
