Ho (UC Berkeley) reports on behalf of the Zwicky Transient\nFacility collaboration:\n\nWe obtained a target-of-opportunity observation of ZTF21aaeyldq/AT2021any\n(Ho et al., GCN 29305) with the Neil Gehrels Swift Observatory starting at\nUT 2021-01-17 (02h29), which is 0.81d after the first optical detection. We\ndetected X-ray emission at the transient position with a count rate 0.0067\nct/s. Assuming a neutral hydrogen column density n_H = 8.12E20/cm2\n(Willingale et al. 2013) and a power-law spectrum with photon index 2, the\nunabsorbed flux is 2.9E-13 erg/cm^2/s. At z=2.514 (A. de Ugarte Postigo et\nal., GCN 29307) the luminosity is 1.5E46 erg/s, typical of GRB afterglows\nat this epoch.\n\nFurther monitoring is planned, and we thank the Swift team for rapidly\nscheduling and executing our observations.\n\n-- \nAnna Ho",
