Possible ball lightning observed during thunderstorm near Rich Valley, Alberta
A possible ball lightning event was recorded near Rich Valley, Alberta at approximately 19:00 LT on July 2, 2025, during a thunderstorm with active lightning. The luminous blue orb moved eastward with the prevailing winds for around 23 seconds before vanishing.
A rare and potentially scientifically significant event unfolded in Rich Valley, Alberta on the evening of July 2, when a local couple captured video footage of what appears to be ball lightning, a poorly understood atmospheric electrical phenomenon.
According to eyewitnesses Ed and Melinda Pardy, a glowing orb approximately 1–2 m (3.3-6.6 feet) in diameter appeared just above ground level shortly after a cloud-to-ground lightning strike. The object hovered around 6–7 m (20-23 feet) above the surface for 23 seconds before it disappeared with a faint “pop” sound.
The phenomenon occurred during a thunderstorm marked by multiple lightning discharges and tornado watches in effect for central Alberta. The blue-colored orb contrasts with typical fire-orange plasma and was described as a clear, contained sphere.
Frank Florian, senior manager of planetarium and space sciences at TELUS World of Science in Edmonton, commented that the video is among the most compelling visual records of a suspected ball lightning event. He noted that while plasma can occasionally persist briefly after a lightning strike, the duration and shape in this case may support a ball lightning classification.
Some weather experts and storm chasers have offered alternative interpretations. A Canadian storm chaser who contacted the video’s author reported that the phenomenon occurred facing north-east, toward an east-west road approximately 1 km (0.62 miles) from the observer’s location, where power lines are clearly visible.
Based on extensive storm experience, the individual suggested the orb was likely caused by a power-line arc, a slow-moving, lightning-induced electrical discharge progressing along the wires. The observed “pop” at the end of the event is consistent with arcing terminations, and lens flare analysis in the video reportedly shows two contact points typical of such discharges.
Other online analysts proposed a Jacobs ladder effect, an upward-moving arc between high-voltage lines enhanced by strong eastward winds. This matches the orb’s observed motion, as the glowing object drifted in the same direction as the prevailing wind. Geolocation efforts placed the event west of the junction between Township Road 564 and Range Road 31, in line with the presence of regional distribution lines.
These interpretations remain unconfirmed but align with known arc plasma behavior and historical misidentifications of ball lightning. Despite skepticism, observers acknowledged the video’s authenticity and importance, with one stating: “I can’t say with 100% certainty that it isn’t ball lightning, but I’d bet the house on it being an arc.”
Ball lightning is a rare and elusive manifestation of atmospheric electricity, characterized by luminous spheres typically appearing during or after thunderstorms. These orbs may hover, drift, or even pass through windows and structures. Durations vary from less than a second to over a minute, and some end with an explosive sound or vanish silently.
Scientific models of ball lightning remain diverse and largely unverified due to the rarity of confirmed observations. Leading hypotheses include vaporized silicon particles forming plasma balls, microwaves trapped within spherical structures, and aerosol-mediated nanobattery reactions. Despite centuries of anecdotal reports, few recorded incidents exist, with one notable spectrum-capture case from 2014 providing partial optical data.
Media reports indicate that researchers from the University of Calgary have contacted the witnesses for further information. If confirmed, the video may contribute valuable data to the study of ball lightning or lightning-induced arc phenomena.

I am replying to put the case that the Pardy “Ball lighting” in Rich Valley Alberta may not the
travelling arc theory along a wire. The Pardy Ball is huge compared to the arc along the wire seen above. Also I noted from the video frames that the shape is by no means spherical like lens flaring and has a definite shape suggestive of vortex breakdown seen in experimental vortex generator used to model dust devils and the like. This is in accord with my published theory on ball lightning. The arc theory proponents have to demonstrate that the power line coincided with the location where the Pardy’s saw the fireball and there is likely arc heating on the wires and posts. An arc was noted as a power outage by the power company-was it?
Hence Ed and Melinda Pardy could well be right-and it is very likely ball lightning and not a transformer arc. l have studied ball lightning for my MSc thesis in physics and had various articles, two books published such as Weather-a publication of the Royal Meteorological Society and others. In my opinion, this is best explained by the fireball vortex theory. That is the combustion of trapped aerosols and flammable gas inside axisymmetric breakdown of a columnar vortex like other canonical vortices such as dust devil. Vortex breakdown is a critical flow transition with sudden sideways expansion of a vortex funnel forming a “bubble”. The bubble is actually swirling air flames with a reverse axial flow with stagnation (slow moving recirculation zones) This model explains several properties of ball lighting as I document in my writing. The vortex was spawned by lightning (5kA-400KA) creating both vorticity and a buoyant updraft of heated air. Any trapped material especially plant crops that would carbonise (soot) and reach high temperatures becoming blue/white hot or incandescent. As this material cools the light would go out and the vortex would become invisible and decay. The reduced upward flow would shift the vortex breakdown down stream (is upwards) as observed in experimental vortex chambers. This lift-off effect was observed in the video frames. The wine glass shape was also seen in the video frames ie the small diameter cylindrical funnel leads to the bubble and the out the large diameter upper funnel. This leads me to think that the sighting is genuine and if it is, it is one of the best available-if not the best.
Thanks, Peter!
