What are these objects?

There are two bright objects near the north star. We could guess they are meteors or satellite glints, but if that was the case, we should have seen them also at Haleakala. The fact that these objects are at a low altitude north to Mauna Kea but still not seen at Haleakala implies that these objects are very low.

I don't know but perhaps the long faint line(s) on the very next image provide some sort of clue:

I'm not sure about that. I think that the long line is the international space station, and it appears both at Haleakala and Mauna Kea. It's hard to get parallax of that one because it is just a long line which doesn't have a "handle". Anyway, that object seems to be at about the same order of the altitude of the object from my previous post, which is several hundreds kilometers.

These seems to be the the ISS.
Below is the image of ISS track, though few hours later then that of MK image.

Tilvi,

Your charts show that it is the ISS on the second picture, but it cannot be the ISS in the first one. The two objects in the first frame are much lower.

Here are the two images from MK & HL. Circled are the objects seen in both images with a time delay of ~4 minutes. My primary guess is that it might be HST, ISS or ....?

Are these objects airplanes? Below two images at HL station on two different consecutive nights shows the objects almost at same location (left of constellation capricorn) on the image, though with some time difference.

These objects aren't airplanes. I am almost sure this is an Iridium satelite.
