When, from where can I observe the ISS (or ATV or ...) crossing the disk of the Moon or (with special equipment for eye protection the Sun) using Calsky ?
Go to http://www.calsky.com/
Register indicating your favorite place of observation (Home ...) with the Google Map
For ISS click under "Current Topics"
on"See the International Space Station ISS"
"Select start of calculation" :
Indicate a period "2 weeks" eg.
Don't click on GO !
You may like to see thoses 2 links :
"# 2-day map where ISS crosses the sun in Google Map"
"# 2-day map where ISS crosses the moon in Google Map"
Then in :
"Select satellite events for your location"...
Check only :
"Close fly-bys of satellite with sun, moon, planets, and stars" using 5°
"Only Sun/Moon events: Display transits/encounters only with the Sun or Moon, but not ..."
You are now in a page with a list of close encounters or transits
Why 5 ° ?
As the orbit mais change a lot in a few days, this assure you will have all the possibilities. Print the page and come back in Calsky later, closer to the event...
If transit confirmed on a ligne of the table (with all the parameters you can
imagine, including direction of the transit) then in column "Object (Link)"
click on "ISS"
In the new page :
"Select start of calculation"... OK
"Select duration" ... OK but sometimes little short, adjust
"Select interval" Ok
Don't click yet on GO !
Now in the 3 colums of the green table :
"Output size" 800
"Realism (e.g. show Planets/Moons)" otherwise you will just see stars !
"Vertex is up" Sun and Moon as seen by eye
"Field of View" 1°
Now click Go ...
If you have followed all the steps you shoud see something like this (Sun) !
Good luck with seeing !
