Upward Streamer Photo

The upward streamer photo looks like a reflection of the main bolt in the lens of the camera (a lens flare), not a positive leader. It even seems to be obscured by an object, just like the main bolt is partially obscured by a tree. Please review the description of that photo since it might be inaccurate. 88.220.51.36 (talk) 14:16, 22 May 2023 (UTC)[reply]

Here's what a lens flare may look like on an iPhone 8 Pro: https://i.imgur.com/6GtLxxm.png 185.238.206.92 (talk) 15:30, 22 May 2023 (UTC)[reply]

I agree that the "upward streamer" appears to be a camera artifact, either caused by a lens flare/reflection or the camera sensor being oversaturated which can create a similar artifact as explained here: https://ztresearch.blog/2017/05/16/blinded-by-the-light/

Upward connecting leaders are generally only seen within around 50m of the main discharge, and they emanate from the tops of pointed objects, and not from a flat object some distance away from the main bolt. PurpleDiana (talk) 04:00, 20 October 2023 (UTC)[reply]

I also agree that this is not an upward streamer. I get these "ghost" lightning bolts all the time when filming lightning. It's just lens flare. On top of being too far from the main bolt and not being from a pointy object, the streamer in question looks too curved. Styro.drake (talk) 01:39, 16 January 2024 (UTC)[reply]

There is an informational error under flashes and strikes: discharge: return stroke: last paragraph. Article states "The core temperature of the plasma during the return stroke may exceed 50,000 K." Unit of measure is wrong. Please change 50,000 K to 50,000 F.

Done I've also added the Celsius equivalent via the convert template. Thanks, Lewcm Talk to me! 13:45, 15 December 2023 (UTC)[reply]

Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near-instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type. The three main types of lightning are distinguished by where they occur: either inside a single thundercloud (intra-cloud), between two clouds (cloud-to-cloud), or between a cloud and the ground (cloud-to-ground), in which case it is referred to as a lightning strike. Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge heat suddenly to very high temperatures. It is often heard a few seconds after the lightning itself. Thunder is heard as a rolling, gradually dissipating rumble because the sound from different portions of a long stroke arrives at slightly different times. This photograph shows strokes of cloud-to-ground lightning hitting the Mediterranean Sea close to Port-la-Nouvelle in southern France.
