Physics of the Chelyabinsk bolide [PDF]
Astronomical School’s Report, 2013 Shown, that estimations of the Chelyabinsk body size order of 20–30 m (15/02/2013 phenomenon), publishing in the press, are overstated significantly. Estimations of its explosion height are wrong. On the basis of the destructions by action of the shock wave, the height of explosion must be no more than 10–12 km. We think, that the Chelyabinsk meteorite

Global Infrasonic Monitoring of Large Bolides. [PDF]
, 2001 Using recent infrasonic data (1995-2001) and older infrasonic data recorded by AFTAC (1960-1974), we have refined our estimates of the global influx rate (cumulative influx) of large bolides with sufficient strength to deeply penetrate the atmosphere ...

Oceans, Lakes, and Stromatolites on Mars
Advances in Astronomy, 2020 Billions of years ago, the Northern Hemisphere of Mars may have been covered by at least one ocean and thousands of lakes and rivers. These findings, based initially on telescopic observations and images by the Mariner and Viking missions, led ...

Observation of three twilight bolides in August, 2013 from Galicia, NW of Spain [PDF]
, 2014 The Spanish Meteor Network (SPMN) is dedicated to the study of fireballs and bolides which may cause meteorite falls on our planet. These meteorites allow us a better understanding of other bodies from the Solar System and that is why we operate 25 ...
