X-ray Outburst of Aql X-1 indicated by the The Neil Gehrels Swift Observatory
Abstract
An optical brightening of Aql X-1 was reported by ATel #15401 on 27th May 2022. Following this we requested The Neil Gehrels Swift Observatory for monitoring observations of Aql X-1. Quick look data analysis results following Evans et al. (2009, MNRAS, 397, 1177) indicate that the unabsorbed flux in the 0.3-10 keV band using the XRT shows an increase from 2.98(0.23,-0.19) X 10^-9 erg/cm2/s to 4.29(0.31,-0.26) X 10^-9 erg/cm2/s in ~20 hours.
