Satellites

ISS

Here is a link that will allow you to type in your city (in the U.S.) and get pass prediction information for the International Space Station (ISS). Note that this information is location-specific, so your timing for viewing the ISS may vary!

NOTES: Included are only major cities currently in the range of visibility, with maximum spacecraft elevations over the horizon larger than 10 degrees. The data are also valid for suburban regions around these cities, with slight changes in Direction of Movement and Max. Elevation.

Pickup Time: The local time of day that the spacecraft becomes visible on the horizon.

Direction of Movement: The spacecraft will appear in the first direction and travel across the sky, rising to the "Maximum Elevation" and disappearing at the horizon in the second direction shown. These compass directions are understood to embrace an angular field of 22.5 degrees each, with their symbols defined as follows:

 

N:  North    NW:  Northwest    NNW:  North-Northwest    SSE:  South-Southeast

E: East SW: Southwest WNW: West-Northwest ESE: East-Southeast

S: South NE: Northeast WSW: West-Southwest ENE: East-Northeast

W: West SE: Southeast SSW: South-Southwest NNE: North-Northeast

J-Track Satellite Tracking is a nice site that will provide you with information on other satellite passes, such as the Hubble Space Telescope (HST) and Chandra X-Ray Observatory.

Heaven's Above is a site that provides you with all the information you need to observe satellites such as the International Space Station and the Space Shuttle, spectacular events such as the dazzlingly bright flares from Iridium satellites, as well as a wealth of other spaceflight and astronomical information. Not only does the site provide the times of visibility, but also detailed star charts showing the satellite's track through the heavens. All pages, including the graphics, are generated in real-time and customized for your location and time zone.

Radiant positions are listed in right ascension and declination coordinates. The column "V" is the velocity in kilometers per second. "Code" is the abbreviation for the shower that observers should use when reporting meteor observations. Periodic showers are listed as "var" under the ZHR column.

More information about meteor showers is available from the American Meteor Society.
