  The lunar impact claimed by Zuluaga et al. (2019) during the total eclipse of
21 January has been discussed widely by his research group, introducing some
results from the technique of gravitational ray-tracing. A similar event of
magnitude 6 was observed visually by the author during the eclipse of 19 years
before, that was published under the name of Padua event (Sigismondi and
Imponente, 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 a
phenomenon after 19 years deserves some investigation about known active meteor
shower on Jan 21 with radiant comprised between the solar longitude 300.7
degrees of January 21 and +/- 60 degrees and declination also departing no more
than 60 degrees from the solar one. The amount of 60 degrees is the FWHM of a
simple modulated probability model on the visibility of a lunar meteor impact
with the cosine of the angle comprised between the line of sight and the normal
to the lunar surface. The candidate of this search is the daytime shower
Sgr/Cap DSC115 with meteoroid velocities around 26 km/s.
