A Search for Meteoroid Lunar Impact Generated Electromagnetic Pulses
Lunar white light flashes associated with meteoroid impacts are now regularly observed using modest optical instrumentation. In this paper, we hypothesize that the develo**, optically-dense hot ejecta cloud ...

Quantitative Comparison of a New Ab Initio Micrometeor Ablation Model with an Observationally Verifiable Standard Model
The Arecibo UHF radar is able to detect the head-echos of micron-sized meteoroids up to velocities of 75 km/s over a height range of 80–140 km. Because of their small size there are many uncertainties involved...

Estimated Visual Magnitudes of the EISCAT UHF Meteors
We have investigated the conditions for simultaneous meteor observations with the EISCAT UHF radar system and telescopic optical devices. The observed characteristics of 410 meteors detected by all three UHF r...

Physical Characteristics of Kazan Minor Showers as Determined by Correlations with the Arecibo UHF Radar
In the northern hemisphere, the month of February is characterized by a lack of major meteor shower activity yet a number of weak minor showers are present as seen by the Kazan radar. Using the Feller transfor...

Observations of the Crab Pulsar during an Occultation by the Solar Corona
WE have measured the difference in time of arrival between individual pulses from NP 0532 (refs. 1 and 2) in frequency bands at 112, 142 and 170 MHz with the 300 foot telescope of the National Radio Astronomy Obs...

Identification of two solar X-ray sources at the 22 September 1968 total eclipse
Study of nearly 200 records of radio signal strength indicates that a major portion of the ambient D layer absorption on 22 September 1968 can be attributed to two strong X-ray sources. The hottest source was ...

Further investigations of solar X-ray sources using D-layer ionization behavior during eclipses
Radio absorption records obtained in or near the zone of totality at two solar eclipses (May 30, 1965 and July 20, 1963) have been examined in detail. It is concluded that all major radio absorption changes du...

Identification of a solar X-ray source using D layer ionization behavior during an eclipse
Semi-quantitative reports of shortwave radio reception during the 12 November 1966 total solar eclipse have been used to determine the characteristics of a major source of D layer ionization. An effective elec...
