International Space Station Visible Tonight (6 minutes!)

Folks - Good news!

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. It will pass about 86 degrees above the horizon!? That's just about directly overhead.

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 gets 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 hams can communicate directly with the ISS or through one of its transponders. The ISS will be visible for 7 minutes and should be a good viewing and becomes visible directly from the Northwest and disappears towards the Southeast.

Time: Thu May 30 8:23 PM

Visible: 6 min

Max Height: 86°

Appears: 10° above NW (from 315 degrees)

Disappears: 17° above SE (toward 135 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 this 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.
