We report on the transient event labelled as TCP J05074264+2447555 which, recently discovered towards the Taurus region, was suddenly recognized as a microlensing event with a lens located at only 380 pc from Earth, thus making it the closest microlensing event observed so far. The event was located towards the anti-galactic center where the probability of occurrence of such events is extremely low. We also discovered planetary features and found that the lens is constituted by an Earth-like planet (Feynman-01 aka the Halloween super Earth) with most likely mass of 9.2 $\pm$ 6.6 $M_{\oplus}$ orbiting a $\simeq 0.25 M_{\odot}$ star. Future observations will allow to further constrain the lens parameters.
