Time/Frequency Analysis of Terrestrial Impack Crater Records [PDF]
The terrestrial impact cratering record recently has been examined in the time domain by Chang & Moon (2005). It was found that the ˜ 26 Myr periodicity in the impact cratering rate exists over the last ˜ 250 Myrs.

The sporadic radiant and distribution of meteors in the atmosphere as observed by VHF radar at Arctic, Antarctic and equatorial latitudes [PDF]
Results are presented of a study of the temporal and spatial variability in meteor count rate observations from three VHF meteor radars. These radar are located in the Arctic (at Esrange, 68° N), in the Antarctic (at Rothera, 68° S) and near ...

Determination of meteor-head echo trajectories using the interferometric capabilities of MAARSY [PDF]
During the flight of a meteoroid through the neutral atmosphere, the high kinetic energy is sufficient to ionize the meteoric constituents. Radar echoes coming from plasma irregularities surrounding the meteoroids are called meteor-head echoes, and ...

THE HALF-YEAR MONITORING OF METEOROID INFLUX TO THE NEAR-EARTH SPACE BY TV-OBSERVATIONS
The Astronomical Institute of Russian Academy of Science provides TV-meteor observations since 2000. We began them with hybrid camera for Space Control Survey, but now we use 6 simple wide-angle Patrol Camera (PatrolCa) for every-night monitoring of ...
