Columbia South Carolina: Rhythmic Blue-Green Light Pulses and Power Outage Over Broad River
On 26 September 2009 between approximately 01:00 and 02:40, three witnesses at a condominium complex on Broad River Road in Columbia, South Carolina, observed a rhythmic phenomenon originating from within or above the 1,100-foot cloud ceiling over the Broad River, approximately 600 feet from their location. A machine-like humming sound rose to a peak and then declined in three-second cycles over approximately ten minutes, synchronized with pulsating blue-green-white light that illuminated the entire area nearly to daylight intensity.
All plugged-in electrical appliances — including those switched off — glowed dimly during the cycles. Landline telephones ceased functioning. A brief ozone smell was detected. After the phenomenon subsided, electrical power failed completely and was not restored until 02:40. Sirens were audible from multiple directions across the city.
The three witnesses — pseudonyms Holden Davidson (a paramedic and former Navy aircraft carrier tower controller on the USS Nimitz), his sister Allison Taylor (a registered nurse), and her 23-year-old son Levi Briggs — provided consistent accounts with no contradictions. MUFON/BAASS investigation confirmed that the local utility SCEG reported no transformer failures in the event area on that date and noted that all local infrastructure uses underground lines with ground-mounted transformers. Shaw Air Force Base confirmed no flights after 23:30 on 25 September. Columbia police, Richland County Sheriff, and Columbia Fire and Rescue had no calls or incidents matching the event location and time.
Background
The Columbia HUM incident of September 2009 stands out among UAP-adjacent cases for combining the absence of a visible structured craft with pronounced electromagnetic effects on the local power grid, household electronics, a rhythmic acoustic signature, and a pulsating luminous phenomenon from within or above the cloud layer.
The Incident
Three witnesses occupied a condominium on Broad River Road, with the Broad River approximately 600 feet to the southeast. Weather conditions that night included a cloud ceiling of 1,100 feet, rain, 73°F, 9.2 mph winds, and 2.5-mile visibility.
Holden Davidson (pseudonym), a paramedic and former U.S. Navy tower controller aboard the USS Nimitz, was alone and awake when the phenomenon began at approximately 01:00. His sister Allison Taylor (a registered nurse) and her son Levi Briggs (age 23) soon joined him outside.
The Phenomenon
The event presented as a repeating cycle lasting approximately three seconds, repeated for roughly ten minutes:
- A machine-like humming sound that built to peak intensity then declined
- A blue-green-white light pulsing in synchronization with the sound
- At peak intensity, the light illuminated the entire area to near-daylight levels
- All plugged-in electrical appliances—including those switched off—glowed dimly
- A brief ozone-like smell was detected by Davidson
The source appeared to be located within or above the cloud layer to the southeast, directly over the Broad River. No structured craft was visible.
After the cycling ceased, the area's electrical power failed completely and was not restored until 02:40. Landline telephones were inoperative throughout the outage. Sirens from emergency vehicles were audible from multiple directions across the city.
Investigation Findings
- SCEG (electric utility): no transformer failures recorded in the event area; all local transformers are ground-mounted with underground distribution lines, ruling out overhead line contact
- Shaw Air Force Base: no flights after 23:30 on 25 September 2009
- Columbia City Police: no calls from the sighting area at the event time
- Richland County Sheriff: no entries for the witness address
- Columbia Fire and Rescue: no dispatches to the area
- Active railway tracks within one mile were examined as a potential source but ruled inconclusive
- Natural phenomena (thunderstorms, lightning) excluded based on the precisely rhythmic three-second cycling and the effect on household electronics
- No physical ground traces, impressions, plant damage, or equipment damage were found
- No contradictions were identified in the three witnesses' accounts; a hoax scenario was excluded given the scale of the electromagnetic effects
