ISS By Day

[MorningMajor]

Are any of the daytime passes of the ISS visible? - Or is this a REALLY stupid question?

[Naz]

The only stupid questions are the ones you don't ask Unfortunately no day time passes of the ISS are visible. Have a look at Heavens-Above Home Page You have to register, enter your location, then all visible passes will be shown.

MM its simply not that bright compared to daylight.

thats why the ambient sky must be dimmer than the reflected light to be able to see it.

Thought not, just wondered if occasionally it would be angled enough for sun the reflect off it as it does of planes - but then again it's a lot higher than your average jumbo!!

Naz, thanks, have already registered and just wondered if they ever list a day time pass - now I know!

The heaven-above site does list any passes that it considers bright enough to see during the day. Never tried to look but may as well give it a go.

On the site click Edit Manually.

Enter your Latitude and Long ( the long is -ve if you are West of the meridian.), then say you are in the London time zone - think it is listed as GMT 0 and click Save.

Then click Daytime Passes of the ISS.

If H-A thinks there are any they will be listed.

Think that "All Passes" may list daytime ones as well but many may not be bright enough.

Heavens Above list as the first option, "All Visible" passes and further down "All Passes including daylight and invisible passes" These would include night time passes when the ISS flies through the Earths shadow. The only "daytime passes" that are visible are the ones that occur when the Sun is below the horizon and the sky has dimmed a little.

There are no stupid questions, only stupid answers.
