Power systems: Voltage corrections may be required, false alarms triggered on some protection devices. Other systems: Induced pipeline currents affect preventive measures, HF radio propagation sporadic, satellite navigation degraded for hours, low-frequency radio navigation disrupted, and aurora has been seen as low as Alabama and northern California (typically 45° geomagnetic latitude). Spacecraft operations: May experience surface charging and tracking problems, corrections may be needed for orientation problems. Power systems: Possible widespread voltage control problems and some protective systems will mistakenly trip out key assets from the grid. Other systems: Pipeline currents can reach hundreds of amps, high frequency radio propagation may be impossible in many areas for one to two days, satellite navigation may be degraded for days, low-frequency radio navigation can be out for hours, and aurora has been seen as low as Florida and southern Texas (typically 40° geomagnetic latitude). Spacecraft operations: May experience extensive surface charging, problems with orientation, uplink/downlink and tracking satellites. Some grid systems may experience complete collapse or blackouts. Power systems: Widespread voltage control problems and protective system problems can occur. The scales have numbered levels, analogous to hurricanes, tornadoes, and earthquakes that convey severity.
The scales describe the environmental disturbances for three event types: geomagnetic storms, solar radiation storms, and radio blackouts. They were introduced as a way to communicate to the general public the current and future space weather conditions and their possible effects on people and systems. Anything below 90 will be closer to the horizon line indicated by zero.The National Oceanic and Atmospheric Administration's (NOAA) uses its space weather scales to categorise solar storms. The higher the number of the elevation, the easier it will be to see the station because 90 degrees would be directly overhead. Once a user inputs their location into the NASA site, they'll see the time the station will be visible, the highest point it will reach in the sky, where it will likely appear first and where it will disappear.
in most places.Īdditionally, the best time to view will be before September 20. Over the next few weeks in the United States, the station will be visible in the early morning hours, between 4 a.m. In some areas, the station is visible for up to six minutes but in others sometimes it only passes for a minute or two. Those who wish to see the station can visit the " Spot the Station" site to type in their location and see when the station will pass overhead during its orbit. It moves more quickly than a plane would but not so fast that it's barely visible like a shooting star. The station appears to look like a plane moving quickly and steadily through the sky and it appears simply a speck of light that does not blink. NASA has a website specifically designed to help those interested in seeing the station spot it, it's called "Spot the Station," and has viewing information for thousands of locations worldwide. The station is the third brightest object in the sky and easy to spot from Earth. Night Earth observation from the International Space Station.
