IPN: GCN 31624 (consistent with ZTF22aabjpxh/AT2022cva), The burst was outside the coded field of view of the BAT.
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.
