Comments:

Due to a Sun observing constraint, Swift could not slew to the BAT position until 10:44 UT on 2019 June 14.
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.
UVOT: no detection
