ABSTRACT On 22 September 1979 two optical sensors on U.S. satellite Vela 6911 detected a double-flash of light that appeared characteristic of an atmospheric nuclear explosion conducted over the southern Atlantic or Indian Ocean. It became known as the Vela Incident, Event 747, or Alert 747. An anomaly between the amplitude of the two signals during the second pulse led a U.S. government expert panel established to assess the event to conclude in mid-1980 that a more likely explanation was the… 
The 22 September 1979 Vela Incident: Radionuclide and Hydroacoustic Evidence for a Nuclear Explosion
ABSTRACT This article offers a new analysis of radionuclide and hydroacoustic data to support a low-yield nuclear weapon test as a plausible explanation for the still contentious 22 September 1979
Plutonium and Tritium Production in Israel’s Dimona Reactor, 1964–2020
Abstract Since the early 1960s, Israel has used the Dimona reactor in the Negev Desert for unsafeguarded plutonium production. Estimates of cumulative plutonium production have been very uncertain,
The paper describes continuous intelligence and value for streaming analytics and the current architecture, status, and trend of real-time streaming technology and analytics, and discusses value creation of streaming analytics.

Optical observations of terrestrial lightning by the FORTE satellite photodiode detector
We review data from observations of terrestrial lightning obtained by the FORTE satellite between September 1997 and January 2000. A silicon photodiode detector (PDD) records the intensity-time
Automated Lightning Flash Detection in Nighttime Visible Satellite Data
AbstractThe Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) nighttime visible channel was designed to detect earth–atmosphere features under conditions of low
FORTE observations of optical emissions from lightning: Optical properties and discrimination capability
[1] Lightning type identification of temporally coincident optical-VHF time series event pairs collected by the Fast On-orbit Recording of Transient Events (FORTE) satellite's photodiode detector
An entry model for the Tagish Lake fireball using seismic, satellite and infrasound records
Abstract— We present instrumental observations of the Tagish Lake fireball and interpret the observed characteristics in the context of two different models of ablation. From these models we estimate
