Popis:	We show that the optical flare event discovered by Graham et al. (2020) towards the active galactic nucleus J1249+3449 is fully consistent with being a quasar microlensing event due to a $\simeq 0.1 M_{\odot}$ star, although other explanations, such as that, mainly supported by Graham et al. (2020), of being the electromagnetic counterpart associated to a binary black hole merger, cannot be completely excluded at present. Comment: Accepted for publication on the Monthly Notices of the Royal Astronomical Society Letters - (MNRAS Letter) -, 2020, 5 pages, 2 figures
