ABSTRACT: Unidentified anomalous phenomena (UAP) research has increasingly adopted multi-sensor methods, yet ultraviolet-C (UVC) sensing remains comparatively underutilized. This paper argues that solar-blind UVC detection should be added as a distinct measurement domain in systematic UAP field research. The rationale is atmospheric: ozone and molecular oxygen strongly attenuate solar radiation below approximately 280 nm, producing a low-background spectral region at ground level. A local source emitting in this band may therefore be detected with high contrast even in daylight. Two complementary instrument classes are emphasized. First, non-imaging binary or photon-counting detectors, exemplified by Hamamatsu Photonics UVTRON flame/discharge sensors, provide rapid, inexpensive, high-sensitivity indication of UVC photon events. Nickel-electrode UVTRON models respond over approximately 185 - 260 nm and are engineered to detect weak flame and electrical-discharge emissions with millisecond-scale response. Second, imaging solar-blind systems, exemplified by OFIL Systems’ DayCor UV-Eye camera core, add spatial localization by combining a 240 - 280 nm UV channel with a synchronized visible channel. The proposed UAP architecture uses binary detectors as wide-area sentinels and event triggers, followed by imaging UVC and independent visible, infrared, radar, radio-frequency, acoustic, and environmental measurements for cross-modal validation. The paper distinguishes established UVC physics from UAP-specific hypotheses: UVC emission is not a validated or unique UAP signature. Its scientific value lies in creating a falsifiable test of whether independently tracked anomalous objects or associated atmospheric processes produce repeatable short-wavelength ultraviolet emission. A calibration, false-positive, synchronization, and evidence-grading framework is presented for field deployment and peer review.
