The video clip that is annexed to this text was captured by the NOAA satellite on Wednesday, April 10, 2022. at 2:30 a.m. mountain time.
According to the YouTube user (MrMBB333) who posted this video clip initially, it is a video over the Eastern Pacific that was made while they were observing the weather in this region of the world. According to the YouTuber’s description of the video, something struck his attention as he was hunting for low pressure systems in the eastern Pacific out of curiosity.
Over the ocean, there is something that like a massive triangle. He continues by saying that in his ten years of utilizing NOAA satellites, he has never seen anything like it, therefore to get a better look at it, he pieced together the slides in improved contrast. The eastern Pacific is seen in the video as seen through a NOAA satellite, and what strikes us as surprising is the presence of a sizable, sinister-appearing triangle that was visible for the whole seven-hour period.
Another triangle can be seen in the video, located to the lower right of the larger triangle. Commenting on the video, the author says: “I have never seen anything like it. I’ve used the NOAA satellite consistently every year, multiple times a year, for 10 years – and I’ve never seen anything so super interesting”.
NOTE:
NOAA-19,
NOAA-19,[7] known as NOAA-N’ (NOAA-N Prime) before launch, is the last of the American National Oceanic and Atmospheric Administration (NOAA) series of weather satellites. NOAA-19 was launched on 6 February 2009. NOAA-19 is in an afternoon Sun-synchronous orbit and is intended to replace NOAA-18 as the prime afternoon spacecraft.[8]
Launch
On 4 November 2008, NASA announced that the satellite had arrived at Vandenberg aboard a Lockheed C-5 Galaxy military transport aircraft.[9] Installation of the payload fairing took place 27 January 2009; second stage propellant was loaded on 31 January 2009.[10]
Several attempts were made to conduct the launch.[11][12] The first attempt, 4 February 2009, was scrubbed after a failure was detected in a launch pad gaseous nitrogen pressurization system. The second attempt, 5 February 2009, was scrubbed after the failure of a payload fairing air conditioning compressor, which is also part of the ground support equipment at the launch pad.
The satellite was successfully launched at 10:22 UTC on 6 February 2009 [13] aboard a Delta II flying in the 7320-10C configuration from Vandenberg Air Force Base (VAFB).
Instruments
NOAA-N Prime carries a suite of eight instruments that provides data for weather and climate predictions. Like its predecessors, NOAA-N Prime provides global images of clouds and surface features and vertical profiles of atmospheric temperature and humidity for use in numerical weather and ocean forecast models, as well as data on ozone distribution in the upper part of the atmosphere, and near-Earth space environments — information important for the marine, aviation, power generation, agriculture, and other communities. The NOAA-N Prime primary instruments — the Advanced Very High Resolution Radiometer (AVHRR/3), High Resolution Infrared Radiation Sounder (HIRS/4), and the Advanced Microwave Sounding Unit (AMSU-A) — were all designed for a three-year mission. The Space Environment Monitor (SEM/2) is fitted to the satellite and is composed of Total Energy Detector (TED) and MEPED (Medium Energy Proton and Electron Detector). The Solar Backscatter Ultraviolet Spectral Radiometer (SBUV/2) was designed for a two-year mission, and the Microwave Humidity Sounder (MHS) instrument was designed for a five-year mission.[14] NOAA-19 also hosts Cospas-Sarsat payloads.[15]
Advanced Very High Resolution Radiometer (AVHRR/3)
The Advanced Very High Resolution Radiometer/3 (AVHRR/3) is the primary imaging system and consists of visible, near infrared (IR) and thermal IR channels. The AVHRR, built by ITT, observes vegetation, clouds, and the surface of bodies of water, shorelines, snow, aerosols and ice. The instrument has a scan mirror that continuously rotates and scans the Earth at six revolutions per second to provide continuous coverage.[16]
Solar Backscatter Ultraviolet Radiometer (SBUV/2)
The Solar Backscatter Ultraviolet Radiometer/2 (SBUV/2) instrument is both an imager and a sounder. As an imager, it produces total column ozone maps. As a sounder, it obtains and measures the ozone distribution in the atmosphere as a function of altitude. The SBUV, built by Ball Aerospace, is a long-term monitoring device that takes global measurements and observes how elements in the atmosphere change over time. Each channel on the nadir-pointing SBUV detects a particular near-ultraviolet wavelength whose intensity depends on the ozone density at a particular height in the atmosphere. The SBUV includes a Cloud Cover Radiometer that provides information on the amount of cloud cover in an image and removes the effects of the clouds from the data.[17]
Microwave Humidity Sounder (MHS)
The Microwave Humidity Sounder (MHS), built by EADS Astrium and donated by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), is a five-channel microwave instrument intended primarily to measure profiles of atmospheric humidity.[18]
High Resolution Infrared Radiation Sounder (HIRS/4)
HIRS/4, built by ITT, has 19 infrared channels and one visible channel. The instrument principally measures carbon dioxide, water and ozone. These measurements allow scientists to determine the amount of each of these gases in the atmosphere and the altitude at which they appear.[19]
Advanced Microwave Sounding Unit (AMSU-A)
AMSU-A, built by Northrop Grumman, has 15 channels and continuously scans the Earth’s surface and the atmosphere, measuring naturally emitted microwave signals radiated by the Earth’s surface and atmosphere.[20]
Space Environment Monitor (SEM-2)
The Space Environment Monitor (SEM-2) was built by Panametrics, now Assurance Technology Corporation. It provides measurements to determine the intensity of the Earth’s radiation belts and the flux of charged particles at satellite altitude. The SEM-2 consists of two separate sensor units and a common Data Processing Unit (DPU). The sensor units are the Total Energy Detector (TED) and the Medium Energy Proton and Electron Detector (MEPED).[21]
Advanced Data Collection System (ADCS)
The Advanced Data Collection System (ADCS), provided by CNES in France, measures environmental factors such as atmospheric temperature and pressure and the velocity and direction of ocean and wind currents. Data is collected from various transmitting devices on platforms (e.g., buoys, free-floating balloons and remote weather stations). Transmitters are even placed on migratory animals, sea turtles, bears, and other animals. Data is transmitted to the spacecraft for storage and subsequent transmission from the satellite to the ground. The stored data is transmitted once per orbit.[22]
SARSAT
The Search And Rescue Satellite-Aided Tracking (SARSAT) system. The Search and Rescue Repeater (SARR), built by the Department of National Defense in Canada, and the Search and Rescue Processor (SARP), built by Centre National d’Études Spatiales (CNES), detect distress calls sent from emergency beacons on-board aircraft and boats and carried by people in remote areas. The instruments on the spacecraft transmit the data to ground receiving stations or local user terminals where the location of the emergency signals is determined by Doppler processing.[15]
