Seven small sensors reconstruct a meteor's invisible pressure wave

A second manuscript submitted to Sensors analyzes a double-peaked 0.4-hertz infrasound pulse recorded by seven Raspberry Boom stations after the May 30, 2026 meteor over Cape Cod Bay. Using timing differences between station pairs, the authors found that the directional lines point toward the known fireball and splash region. Distance-versus-arrival-time fits favor a blast altitude around 40–50 kilometers, consistent with NASA's revised optical estimate.

The close, nearly aligned sensor layout could not cleanly triangulate the blast point against the later ocean splash, so the paper uses acoustic energy as an additional test. Representative pressures imply roughly 1.7 to 4.8 times 10^11 joules of acoustic energy, broadly compatible with a fraction of the fireball's reported energy and far beyond what the slowed fragments could deliver at splash. Sensor placement and calibration contribute uncertainty, and the paper remains a submitted preprint—not a UAP detection.

Why it matters

A distributed, synchronized sensor network can turn a mysterious boom into competing physical hypotheses—and can show exactly where its own geometry stops being decisive.

What the source establishes

Fresh submitted manuscript using publicly available citizen-science sensors and NASA event estimates. Source direction and blast interpretation are supported as reported; pressure calibration and sparse station geometry limit precision.
