Strewn Field Simulations and Field Searchs of a Few Latest Bolides Over Hungary - Connection with the Fragmentation Height [PDF]

, 2019
nspired by several unsuccessful field searches on the probable fall locations, we reanal-ised a few most recently observed blowing bolides ap-peared over Hungary on: 18:47:33 UTC 8 April, 2018; 17:31:01 UTC April 06, 2015 (so-called "Easter Bo-

A Comparison of Automated Bolide Detection Methods [PDF]

, 2023
Bolide recording and analysis are crucial so meteoroid fragments can be found, a lightcurve analyzed, and its trajectory calculated. The Spalding Allsky Camera Network (SACN) generates videos and composite images of the night sky that are potential ...

The Utility of Infrasound in Global Monitoring of Extraterrestrial Impacts: A Case Study of the 2008 July 23 Tajikistan Bolide

The Astronomical Journal
Among the various observational techniques used for the detection of large bolides on a global scale is a low-frequency sound known as infrasound. Infrasound, which is also one of the four sensing modalities used by the International Monitoring System ...

Multiparameter Constraints on Empirical Infrasound Period-Yield Relations for Bolides and Implications for Planetary Defense

The Astronomical Journal
How effective are methods for estimating bolide energies from infrasound signal period-yield relationships? A single global period–energy relation can obscure significant variability introduced by parameters such as the atmospheric Doppler wind profile ...

Apache Point Rapid Response Characterization of Primitive Imminent Impactor 2024 RW1

The Astronomical Journal
Imminent impactors may be detected only a few hours before their impact with Earth, providing a brief opportunity to characterize them before impact. We describe the characterization of imminent impactor 2024 RW _1 , which was discovered by the Catalina ...

Fluctuations and symmetry in the speed and direction of the jets of SS433 on different timescales [PDF]

, 2007
ABRIDGED We present new results on the variations in speed and direction of the jet bolides in the Galactic microquasar SS433, from high resolution spectra, taken with the ESO 3.6-m New Technology Telescope almost nightly over 0.4 of a precession cycle ...

BLADE: An Automated Framework for Classifying Light Curves from the Center for Near-Earth Object Studies Fireball Database

The Astronomical Journal
Fireballs (bolides) are high-energy luminous phenomena produced when meteoroids and small asteroids enter Earth’s atmosphere at hypersonic speeds, often resulting in fragmentation or complete disintegration accompanied by significant energy release.

Interception of a bolide ?

, 1997
We present a review of the literature on the subject of a possible collision between the Earthand a meteorite or comet. We emphasize the global effects when sufficient energy is involved.We propose several types of human actions adapted to the physico-chemical nature of thecollider bolide.
