If you are watching the sky on Friday and spot green balloons, think of Iran. The planned release of the balloons is right now, at 1:00 pm Tehran time (GMT +4 1/2 hours).
Our Iranian blogger-friend posted this message:
"Are you mad about what has been happening inside Iran these days? Well then take a deep breath... blow it all into a Green Balloon... and wait until Friday afternoon to send it up to the sky, wherever you are on this planet. Millions of Iranians inside Iran are planning to paint the sky green on Friday exactly at 1pm Tehran time. The non-violent green movement is being cracked down on the ground, so lets take it to the sky."
