ISS Pass as seen from WTOC

MAG = Magnitude ... the lower the value, the brighter the object.  Example, a magnitude of (-2.3) would be as bright as the planet Jupiter (very bright).  A magnitude (0 or +1) would be about the brightness of the stars in the big dipper.

AZ = Azimuth ... that is the direction in the sky

= Altitude ... this is the height in degrees above the horizon.  An overhead pass would have an altitude of 90.

Viewing Tips:
To view the space station, near the times posted above, watch for the appearance of a bright looking star.  It will move at a rate similar to that of a high flying jet.  Don't confuse the station with passing aircraft.  The space station will not blink or flash but passing aircraft will.  The space station is orbiting the earth at an elevation of about 200 miles at an orbital velocity near 17,500 mph per hour (5 miles per second).  During an overhead pass, the station will take about 10 minutes to transverse the sky.  There will be times when the station will pass into or out of the shadow of the earth when high up in the sky.  When this happens, the station will disappear (or appear) in about a period of 2 seconds.
