“Giant plane”: a photographer records a rare phenomenon in the sky; understand
âGiant jets (GJ) are phenomena that belong to a group called ‘transient light events’ (TLE). TLE are light phenomena of short duration (less than 1 second) which occur above storm clouds, and are associated with the appearance of lightning â, explains Diego Rhamon, graduate of a master’s degree in meteorology from the National Institute for Space Research (inpe). He himself filmed one of these events in Brazil.
The expert explains that among the transient light events, Giant planes are the rarest.
” He is the only one [TLE] Which directly connects the top of the cloud to the ionosphere [uma das camadas da atmosfera]. The lower part describes a narrower structure resembling a tree trunk with a blue / purple color that gradually branches out and turns reddish near the top.
For Diego Rhamon, the fallout from Lucina’s photos is due to the fact that they were done so well – perhaps for the first time. âOther GJs were rated with much lower quality,â he says.
To capture this phenomenon, the viewer needs a night light sensitive camera. “Some security cameras, like those used in Bramon [Rede Brasileira de Monitoramento de Meteoros], they succeeded in recording, but the correct lenses must also be used in the cameras, âexplains the master.
Professional cameras, for example, can be used, provided you have suitable lenses. (On a cell phone, for example, this is not possible).
You can also watch the action with the naked eye, explains Diego Rhamon, âbut it’s very weak, and it’s nice to be in a very dark place.
Another point is that giant planes can be confused with another phenomenon, namely orcs.
âImps are the most common type of TLE and are associated with the appearance of cloud-to-ground lightning, usually of positive polarity. They have a reddish color and several branches are usually seen in their structure. They can occur at altitudes ranging from 30 to 90-100 km [tambÃ©m na ionosfera]explains Diego Ramon.
Because of this similarity in color, the researcher states: âIf an image did not have a very clear definition, and also if there were obstructions covering the underside of a giant airplane (clouds, mountains, buildings), it would be [o jato gigante] It can be confused with the Elf, because the biggest difference in the appearance of the two is in the lower and middle part, âhe assessed.
