AB We discuss here a lunar impact flash recorded during the total lunar eclipse that occurred on2019 January 21, at 4 h 41 m 38.09 ± 0.01 s UT. This is the first time ever that an impact flashis unambiguously recorded during a lunar eclipse and discussed in the scientific literature, andthe first time that lunar impact flash observations in more than two wavelengths are reported.The impact event was observed by different instruments in the framework of the MIDASsurvey. It was also spotted by casual observers that were taking images of the eclipse. Theflash lasted 0.28 s and its peak luminosity in visible band was equivalent to the brightness ofa magnitude 4.2 star. The projectile hit the Moon at the coordinates 29.2 ± 0.3 ◦S, 67.5 ± 0.4◦W. In this work we have investigated the most likely source of the projectile, and the diameterof the new crater generated by the collision has been calculated. In addition, the temperatureof the lunar impact flash is derived from the multiwavelength observations. These indicate thatthe blackbody temperature of this flash was of about 5700 K.
