The lunar impact claimed by Zuluaga et al. (2019) during the total eclipse of21 January has been discussed widely by his research group, introducing someresults from the technique of gravitational ray-tracing. A similar event ofmagnitude 6 was observed visually by the author during the eclipse of 19 yearsbefore, that was published under the name of Padua event (Sigismondi andImponente, 2000a,b) and a video was obtained independently by Gary Emerson(Cudnik, 2002) in the US at the same time. The remarkable repetition of such aphenomenon after 19 years deserves some investigation about known active meteorshower on Jan 21 with radiant comprised between the solar longitude 300.7degrees of January 21 and +/- 60 degrees and declination also departing no morethan 60 degrees from the solar one. The amount of 60 degrees is the FWHM of asimple modulated probability model on the visibility of a lunar meteor impactwith the cosine of the angle comprised between the line of sight and the normalto the lunar surface. The candidate of this search is the daytime showerSgr/Cap DSC115 with meteoroid velocities around 26 km/s.

Lunar impacts during eclipses separated by a Metonic cycle on Jan 21,  2000 and 2019: a possible origin from daytime Sagittarids/Capriconids meteor  shower
