      XRT: The source is below the RASS limit but does not show definitive signs of fading. This is most likely the afterglow, given also the reported redshift of z=2.14 (Saccardi et al. GCN Circ. 33281) but further observations are required to assess for fading.

LCOGT (1m, candidate)     Note that this source is near the Galactic plane (lat=2.38 deg) and was detected as a 64 s image trigger, which raises the possibility that this is a Galactic transient. We would name this source Swift J1552.8-5055 if it is not a GRB.

XRT: One uncatalogued X-ray source has been detected at a position consistent with the GRB optical afterglow candidate ZTF22aabjpxh/AT2022cva (Ho et al., GCN Circ. 31619). The X-ray source is below the RASS limit and shows no definitive signs of fading.

While the BAT data alone is insufficient for us to make a definitive judgement as to the nature of the source, our assessment of these data suggests that the event was more likely a short GRB rather than a previously unknown Soft Gamma Repeater (Swift J1851.2-6148). See GCN 29332 for details.

XRT: Ten uncatalogued X-ray sources have been detected, however none of them is above the RASS limit or shows definitive signs of fading. Therefore, at the present time we cannot identify which, if any, is the afterglow.

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.
