Enhanced activity of OJ 287 after its emergence from Swift Sun constraint
Abstract
We have observed the blazar OJ 287 which has emerged after being Sun constrained for 100 days with the Neil Gehrels Swift observatory. Between 2018 September 26 and October 6 it showed enhanced activity at all wavebands in comparison to its last Swift observation on 2018 June 12. On 2018 September 26, its UVOT W2 magnitude was at 14.58 +/- 0.04 (corrected for Galactic reddening, or a flux level of (1.51+/-0.04)e-11 erg/cm2/s), which is 0.25 magnitudes brighter than during its last Swift observation, and the brightest level since February 2018.
