Not So Fast: A New Catalog of Meteor Persistent Trains
L. E. Cordonnier, K. S. Obenberger, J. M. Holmes +2
This paper presents the results of a nearly two year long campaign to detect and analyze meteor persistent trains (PTs) - self-emitting phenomena which can linger up to an hour aft…
Spatially Resolved Observations of Meteor Radio Afterglows with the OVRO-LWA
S. S. Varghese, J. Dowell, K. S. Obenberger +3
We conducted an all-sky imaging transient search with the Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) data collected during the Perseid meteor shower in 2018. T…
Broadband Imaging to Study the Spectral Distribution of Meteor Radio Afterglows
S. S. Varghese, J. Dowell, K. S. Obenberger +2
We present observations of 86 meteor radio afterglows (MRAs) using the new broadband imager at the Long Wavelength Array Sevilleta (LWA-SV) station. The MRAs were detected using th…
Testing the Radiation Pattern of Meteor Radio Afterglow
S. S. Varghese, K. S. Obenberger, G. B. Taylor +1
Radio emission from meteors or meteor radio afterglows (MRAs) were first detected using the all-sky imaging capabilities of the first station of the Long Wavelength Array (LWA1). I…
Altitudinal dependence of meteor radio afterglows measured via optical counterparts
K. S. Obenberger, J. M. Holmes, J. D. Dowell +4
Utilizing the all-sky imaging capabilities of the LWA1 radio telescope along with a host of all-sky optical cameras, we have now observed 44 optical meteor counterparts to radio af…
Rates, Flux Densities, and Spectral Indices of Meteor Radio Afterglows
K. S. Obenberger, J. D. Dowell, P. J. Hancock +4
Using the narrowband all-sky imager mode of the LWA1 we have now detected 30 transients at 25.6 MHz, 1 at 34 MHz, and 93 at 38.0 MHz. While we have only optically confirmed that 37…
Dynamic Radio Spectra from two Fireballs
K. S. Obenberger, G. B. Taylor, C. S. Lin +3
We present dynamic spectra from the LWA1 telescope of two large meteors (fireballs) observed to emit between 37 and 54 MHz. These spectra show the first ever recorded broadband mea…
Detection of Radio Emission from Fireballs
K. S. Obenberger, G. B. Taylor, J. M. Hartman +9
We present the findings from the Prototype All-Sky Imager (PASI), a backend correlator of the first station of the Long Wavelength Array (LWA1), which has recorded over 11,000 hour…
