Scientific Coalition for UAP Studies
Also known as SCU, Scientific Coalition for UAP Studies (SCU)
The Scientific Coalition for UAP Studies is a U.S. non-profit of scientists, engineers and investigators who apply scientific methods to UAP cases and publish their analyses. Its best-known work is a long forensic report on the 2004 Nimitz encounter, distilled into the 2019 peer-reviewed Entropy paper by Kevin Knuth, Robert Powell and Peter Reali, and earlier reports on the 2008 Stephenville lights and the 2013 Aguadilla video, both co-authored by Powell. It holds an annual conference (Toronto, July 2026) and streams talks and panels.
Its members are mostly private researchers rather than witnesses, and its reports are its own analyses; where official findings exist they can differ. AARO attributed the Aguadilla object to balloons or sky lanterns.

Facts and claims
- claimed SCU describes itself as “a research organization of scientists, researchers, and professionals from across organizations, governments, and industries to scientifically and publicly explore anomalous phenomena known around the world as UAPs, UFOs, USOs, and OVNIs”, and as “not a club or an enthusiast group, but rather it is a think tank”. It is a 501(c)(3) charity and holds an annual conference. Source: explorescu.org (archived)
- claimed Its board is led by its founding members; in November 2026 the board included Robert Powell, Richard Hoffman, Morgan Beall, the astronautical engineer Doug Buettner, the Harvard physicist Laura Domine, Larry Hancock, the astronomer Cameron Pratt and Peter Reali.

- documented Three SCU affiliates, Kevin Knuth, Robert Powell and Peter Reali, published a peer-reviewed estimate of the Nimitz Tic Tac's accelerations in Entropy in 2019, summarising SCU's longer forensic report on the encounter; the radar figures rest on Kevin Day's account, not on radar data.

- claimed Powell says that, unlike Stephenville, where they obtained the radar data, SCU has never been given the Nimitz radar data. — Robert Powell Source: Estimating the flight characteristics of the 2004 Nimitz encounter: SCU panel with Kevin Knuth, Robert Powell and Peter Reali (2021) at 19:50
- documented AARO assessed with high confidence that the 2013 Aguadilla object, which SCU's report had studied, was likely a pair of balloons or sky lanterns drifting over the airport, the apparent high speed being parallax. Source: defensescoop.com (archived)
- claimed Kevin Knuth calls SCU's UAP pattern recognition study probably one of the most important studies ever done on the subject. — Kevin Knuth Source: Kevin Knuth: The Scientific Study of Unidentified Aerospace-Undersea Phenomena (SCU Conference, 2025) at 38:36

People
- Robert Powell (member) — Executive board member, among the founding members who lead the board
- Kevin Knuth (member) — The 2019 Entropy paper lists SCU as his second affiliation
Documents
- Estimating Flight Characteristics of Anomalous Unidentified Aerial Vehicles (Knuth, Powell & Reali, Entropy, 2019) (produced) — Powell and Reali, both SCU board members, co-wrote it, and SCU is an affiliation of all three authors
Incidents
- USS Nimitz “Tic Tac” encounter (analysed) — Its long forensic report on the encounter is the source the Entropy paper summarises
- Aguadilla “Puerto Rico object” (analysed) — Powell co-authored SCU's report on the 2013 Aguadilla video; AARO later attributed it to balloons or sky lanterns
