XRT: Given the low significance of the fading, the faintness of the source, and the fact that low-level variability is not uncommon among X-ray sources, we cannot say with confidence that this is definitely the afterglow of GRB 190610A, however it remains a tantalizing possibility. Due to the faint nature of the object, no further XRT observations are planned.

BAT: This burst occurred during the period of recovering the thermal control system (Barthelmy et al., GCN Circ. 18562). The CZT bias voltage has been reduced to -150v (instead of the normal -200v) and as such the energy scale is not fully calibrated. Therefore, an accurate spectral analysis is unavailable.

Fermi (GBM)     BAT: Despite being near the Galactic Plane and Bulge, both the fast-decaying XRT light curve and Fermi/GBM observation (GCN Circ. 17511) suggests that this source is more likely to be a short GRB than a SGR. In addition, there are no other BAT detections of this source before or since this trigger.

  ~0.959 (VLT: emission from host)   BAT: From the BAT spectrum, this event does not appear to be a short hard burst. The quickly fading X-ray lightcurve, however (to be reported in a later circular), does appear consistent with a SHB, and does not appear to be similar to the lightcurves of SGRs or other Galactic sources.
