I have now lived through a failed coup attempt in Istanbul. In the interest of posterity I am making available the sequence of events as I lived them, based on my Facebook account activity. I live in the Acibadem-Hasanpasha Area on the Asian Side. I am safe.
10:30-11:00 I am watching Borgen S3E1. I get a message from a friend in Greece asking me if I am well. Friend tells me a coup is being attempted
11:00-11:10 I hear the rumbling of what can only be tanks or APCs. I run out. People are congregating. I cannot see the military vehicles, but I can hear them. The people are agitated and when I ask asker? Some of them nob. I go back inside.
11:10-11:30 I call my parents in Greece to make sure to tell them I am safe. I open up the VPN to retain internet access and begin interacting with other friends in turkey to learn news
12:00-12:30 I learn the a curfew has been declared by the coup members. I can still hear cars running. Sporadic honking also, an indicator of support for the government
1:00 Friends report to me that many generals have declared their loyalty to the government (after the fact I learn that it is the most important officer in Istanbul, the commander of the 1st Army). Also that people are congregating at the airport to welcome the President
1:25 I log in to report heavy rifle fire in the area.
1:33 Prayers are called from the Mosques. Political message as well. Mosques are blaring at full volume. I discern the word asker.
1:35 Multiple indicators in the area that the curfew is definitely not obeyed.
1:38 I can faintly hear massive crowds
2:05 I can still hear sporadic gun-fire. But not sure if it is a battle like at 1:25 or celebratory.
2:58 I attempt to go to sleep but I am awakened by a fighter jet either breaking the sound barrier or dropping sonic bombs.
3:20 Lengthy text message received on the phone from the President.
3:38-3:41 Fighters still flying over area.
4:05 Demonstration Continue as I can hear the chants and honking. I can hear helicopters.
4:13-4:23 Last call of prayers from the mosques. Very long announcement follows.
