Pronunciation: [sˈa͡ɪdflaʃ] (IPA) 
Sideflash is spelled as /saɪdflæʃ/. The word is a combination of two words 'Side' which is represented by /saɪd/ and 'Flash' which is represented by /flæʃ/. The 'I' in 'Side' is pronounced as /aɪ/, while 'Fla' in 'Flash' is represented by /flæ/. The 'sh' sound at the end of the word is represented by /ʃ/. Sideflash is a term used to describe a sudden burst of light that appears on the side of an object or scene.
Sideflash refers to a phenomenon that occurs during a lightning strike when a secondary flash ignites from a conductive object located near the primary strike point. This secondary discharge usually emerges from objects that are not directly struck by the main lightning bolt but are in close proximity to it. Also known as a side flash or side splash, sideflash is a frequently observed occurrence during thunderstorms, particularly those with intense electrical activity.
When a lightning bolt strikes a tall structure, such as a tree, building, or utility pole, the massive electrical charge follows the path of least resistance to the ground. However, if there are nearby objects within close range and well-grounded, such as people or other conductive structures, the electrical charge may divert momentarily via an alternate path. This diversion results in a sideflash as a secondary electric discharge jumps to the conductive object.
Sideflashes can pose a significant risk to human safety as they may unexpectedly travel through unintended conductive paths, such as people, and cause injury or worse. Therefore, during thunderstorms, it is crucial to stay clear of tall objects or structures as well as avoid standing near them. It is also advised to seek shelter in fully enclosed buildings or vehicles to minimize the danger of sideflashes.
Understanding the concept of sideflash is essential in lightning safety so that individuals can take necessary precautions to minimize the risks associated with this phenomenon, thereby ensuring personal safety during thunderstorms and electrical storms.
