Another opportunity to spot the International Space Station this evening as it passes over our area in Arizona.

It should be a great pass and hopefully the clouds will be minimal.

Treat your family and friends to a viewing of the International Space Station tonight. I find that even the most non technical family member or friend get a kick out of seeing the station as it moves across the sky at 17,150 MPH - that's 4.76 miles per second - and about 250 miles above us.

If you are an amateur radio operator, take the opportunity to relate how us hams can communicate directly with the ISS or through one of its transponders.

The ISS will be visible for 6 minutes and should be a good viewing and becomes visible directly from the West Southwest and disappears toward Northeast.

Time: Thurs September 17 7:31 PM
Visible: 6 min
Max Height: 55°
Appears: 10° above WSW (from 248 degrees)
Disappears: 11° above NE (toward 45 degrees)

I've also attached an illustration that will help you determine how to use this information. You can watch and track the station in advance at this link:



And, something new! I've attached a chart of the actual pass.

Remember, these times are based on a viewing site from the Mesa area (and within 50 miles). If you would like to generate times from your specific city or town, visit the link and follow the instructions.

If your specific city or town isn’t listed, pick the closest one. The space station is visible for at least a 50 mile (80 km) radius around each of the listed locations.

If you are an amateur radio operator, listen in (or work) on these frequencies:

Voice and SSTV Downlink: 145.80 (Worldwide)

Voice Uplink: 144.49 for ITU Regions 2 and 3

VHF Packet Uplink and Downlink: 145.825 (Worldwide) - easiest to hear

UHF Packet Uplink and Downlink: 437.550

UHF/VHF Repeater Uplink: 437.800

UHF/VHF Repeater Downlink: 145.799 (67 Hz PL Tone)
