Discussion Overview

The discussion revolves around an unusual visual phenomenon observed during a lightning storm, where the observer noted fine vertical lines in their yard following a nearby lightning strike. Participants explore potential explanations, including magnetism and optical effects, while considering the implications of the observation in relation to lightning and its effects.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • The observer describes seeing fine vertical lines in their yard during a lightning storm, speculating whether it could be related to magnetism or the wireless fence around the property.
  • One participant requests more details about the appearance of the lines, asking whether they were hard, well-defined, or soft and fuzzy.
  • Another participant suggests that the lines might have been an optical effect viewed through a glass window, highlighting the difficulty of recalling details under stress.
  • A participant recalls a TV program discussing how some birds perceive magnetic fields, suggesting that the visual aspect might represent an awareness of the magnetic field's gradient rather than a direct view of the field itself.
  • One participant proposes that the lines could be small flaming bits of debris kicked up by the lightning strike or from nearby trees or bushes.
  • Questions are raised about the size and appearance of lightning branches, with one participant noting that they can be small yet still appear reasonably sharp.

Areas of Agreement / Disagreement

Participants express various hypotheses and questions regarding the observed phenomenon, with no consensus reached on the cause or nature of the lines. Multiple competing views remain, including the possibility of optical effects, magnetism, and debris from the lightning strike.

Contextual Notes

Participants acknowledge the limitations of recalling details during stressful situations and the potential for optical illusions in such conditions. The discussion does not resolve the nature of the observed lines or their relation to lightning.

During an intense lightning storm which led to a tornado warning, I saw something in my yard which no one has yet explained. There was ordinary lightning near the ground about 30 feet away. Then I saw the whole front yard filled with fine vertical lines, evenly spaced, maybe a foot or less between them. No sound or feeling of shock or tingling. I couldn't stop to look closer, having to evacuate self and animals. I wonder if it was related to the wireless fence around the property? After reading a lot about lightning, I began to think it was magnetism, which some birds can see due to a substance in the retina. Any serious comments would be welcome.
 
Physics news on Phys.org
I've never heard of such a thing, but that doesn't mean much I suppose. Can you tell us more about these lines? What exactly did they look like? Hard and well defined? Soft and "fuzzy"? Dark or light? How far up did they seem to go? Etc.
 
It's difficult to remember things under conditions like that. It could have been just an optical effect from viewing the lightning through a glass window?

I remember hearing of this on a TV programme. I understood that the 'visual' aspect of the magnetic field was more like an awareness (presented visually) of the gradient / direction of the field than seeing the field at another location. I remember the visual I saw implied the equivalent to a (false) colour gradient over the visual field. It was only a brief item that I saw in a programme about animal migration. (Always suspect anything on TV -even the News)

Welcome to the PF.

I'm very glad you were not hurt. Could it have been small flaming bits of debris kicked up by the ground strike? Or maybe from hitting a tree or bush?

In a number of the clips in this video, you can see small flaming bits of debris...

 
Lightning branches -- how small do the branches get? Is lightning "fuzzy"?

very small and still reasonably sharp ... am at work at present will post a pic of a very close strike to me some years back
looked like I was standing under a big set of tree roots

ohhh ... may be on my storm images page ... will go look

edit found it

much too close for comfort ... that building was around 50 metres away
