Can show more satellites through in-app purchases. "Star Walk: Constellation Finder" from Vito Technology Inc shows both Iridium flares and ISS passes. Satellite Tracker - (ProSat) Displays satellite paths 7 days in advance and operates offline until additional days are needed. Compass view of paths as well as 3D earth view.
Visible pass of the International Space Station and Space Shuttle Atlantis over Tampa, Florida, on mission STS-132, May 18, 2010 (five-minute exposure). An orbital pass (or simply pass) is the period in which a spacecraft is above the local horizon, and thus available for line-of-sight communication with a given ground station, receiver, or relay satellite, or for visual sighting.
Satellite flare. Top: a simulated animation of a typical Iridium flare. Bottom: Both images show a flare of an Iridium satellite. Comet Holmes can be seen in the right image, slightly above the tree branch. Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare".
In astronomy, an analemma ( / ˌænəˈlɛmə /; from Ancient Greek ἀνάλημμα (analēmma) 'support') [a] is a diagram showing the position of the Sun in the sky as seen from a fixed location on Earth at the same mean solar time, as that position varies over the course of a year. The diagram will resemble a figure eight.
An atmospheric window is a region of the electromagnetic spectrum that can pass through the atmosphere of Earth. The optical, infrared and radio windows comprise the three main atmospheric windows. [2] The windows provide direct channels for Earth's surface to receive electromagnetic energy from the Sun, and for thermal radiation from the ...
GOES-17 →. GOES-16, formerly known as GOES-R before reaching geostationary orbit, is the first of the GOES-R series of Geostationary Operational Environmental Satellites (GOES) operated by NASA and the National Oceanic and Atmospheric Administration (NOAA). GOES-16 serves as the operational geostationary weather satellite in the GOES East ...
Solar prominences can be seen along the limb (in red) as well as extensive coronal filaments. An eclipse is an astronomical event which occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer.
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of Earth, totally or partially. Such an alignment occurs approximately every six months, during the eclipse season in its new moon phase, when the Moon's orbital plane is closest to the plane of Earth's orbit. [1]
