Good sightings of the International Space Station on Friday and Sat. evenings over much of the East.

We’re likely to have good sightings of the International Space Station on Friday and Saturday evenings in the vicinity of Washington DC. Monday looks good too.

The secret is the azimuth – it’s way up above the tree line.

Washington PA, I don’t know. Let's check Pittsburgh.

Pittsburgh will be good tonight and definitely Monday.

You can check Washington PA too. Or Rocky Mount VA. Or....

3. It's going right over my house!

What should I actually be looking for?

4. A bright light. You might think it's an airplane, but it's moving faster than an airplane.

Unlike an airplane or helicopter, it doesn't have blinking lights. The light you see is light reflected from the sun.

It generally moves from west to east. It can move from the NW to the SE or from the NE to the SW. But it's never going to be headed east to west.

Because you're looking at reflected sunlight, it becomes visible when the angle formed by the sun, the space station, and you becomes just right. It moves quickly from west to east, and then it suddenly disappears. It has moved out of the sunlight and into the shadow cast by the Earth.

It will be back in another ninety minutes, but by then the angle of the sun is wrong for you to see reflected light. That's why the sightings are just before dawn and just after sunset. You can see it during the day, but it take a special effort. You have to be set up in advance with a telescope or telephoto lens.

In the upcoming sightings I've mentioned here, all you need is your naked eye. You won't need binoculars. I think the sightings are better without binoculars. You get a sense of perspective.

5. Did you see it? It was a great sighting "over" Alexandria.

I'm not sure what path it traced on the ground, since it was just as easily seen in Pittsburgh.

6. I didn't but my family did.

I had to go pick up dinner. Looked at the clock right after I ordered and was like UGH! The said it was really cool.
