These comments: The cropped image at Commons File:Earth-grazing meteoroid, 13 October 1990 (2) TFA.jpg minus the red arrow might make a good first image for the review. While it only captures a portion of the track, it shows the rotating shutter interruptions as described. As noted in the GA and FA appraisals on Wikipedia, the English is excellent as is the attention to detail! Although Wikipedia does not allow original research, the WikiJournals do, so if the authors wish to add any for review, they are more than welcome to! I've noticed that some numbers have included errors while others do not. Would it be more consistent to include errors for each? From the mass and approximate composition of the meteoroid would you estimate its size at about 1 m? Using NASA's Near Earth Object (NEO) Program map and data, see File:SmallAsteroidImpacts-Frequency-Bolide-20141114.jpg, a fireball incidence of about 27 a year and the low detection rate of meteoroids of ~1 m size, unfortunately, it seems earlier or subsequent detections are unlikely. Has anyone checked for either in the European Fireball Network? I would guess this meteoroid was not a Draconid or an Orionid? I'm guessing no spectroscopy is available? From the analysis of the encounter, is there anything to suggest that the heliocentric orbit of the meteoroid is progressing from being a Mars crosser to more of an Earth crosser, or is it equally likely that the meteoroid will be sent back outward in subsequent encounters? Brief overview of the paper and its main findings On 13 October 1990, meteoroid EN131090, with an estimated mass of 44 kg, entered the Earth's atmosphere above Czechoslovakia and Poland and, after a few seconds, returned to space. Observations of such events are quite rare; this was the second recorded using scientific astronomical instruments (after the 1972 Great Daylight Fireball) and the first recorded from two distant positions, which enabled the calculation of several of its orbital characteristics. The encounter with Earth significantly changed its orbit and, to a smaller extent, some of its physical properties (mass and structure of its outer layer). Please provide a brief overview of the paper and its main findings.

Major and minor points Using NASA's Near Earth Object (NEO) Program map and data, see File:SmallAsteroidImpacts-Frequency-Bolide-20141114.jpg, a fireball incidence of about 27 a year and the low detection rate of meteoroids of ~1 m size, unfortunately, it seems earlier or subsequent detections are unlikely. Has anyone checked for either in the European Fireball Network? This should be the main substance of your review and should bring up any weaknesses, inconsistencies, things that need to be clarified or questions you have for the authors.

From the analysis of the encounter, is there anything to suggest that the heliocentric orbit of the meteoroid is progressing from being a Mars crosser to more of an Earth crosser, or is it equally likely that the meteoroid will be sent back outward in subsequent encounters?
