Description
The transient LMXB and 11 Hz pulsar currently in outburst in Terzan 5 (ATEL #2919, #2920, #2922, #2924, #2932) has been recently observed to show at least one eclipse of 511 s duration (ATEL #2929). We have checked the Chandra lightcurves (readout streak and dust-scattered halo) from the 2000 July 24 observation (Heinke et al. 2003, ApJ, 590, 809), and find no eclipses in the 45 ks (12.5 hour) observation.
