According to turkish newspaper Hurriyet (October 15th, 2007) an investigator working in the Ottoman archives found a letter sent by Kirkuk Post Office Manager Seyit Hasan to Sultan Abdulmecid dated June 27th, 1856. Here is a quick translation of the letter:
"God save the Ottoman land from natural disasters. Amen. Since the 15th day of may in the 74th year (islamic calendar?) temperatures in the region increased day by day up to more than 40 degrees. Due to intense heat 250 people living in houses and tents have died. Inhabitants of 4 cities started living in cellars and wells. Summer crops started to burn due to intense heat. 6th of June, on friday night, around midnight [here is a description of an astronomical event that I could not translate because it is in ottoman]. After this, more terrible than lightning some noises were heard as if "kudret topu" (kind of an Ottoman gun) was fired three times. For 15 minutes noises were heard as if there was a gun training. Then fireballs bright as full moon were seen and disapperaed after 5-6 minutes. After 1-2 hours later another star was seen as a meteor?
Until now no one has ever seen such a rainbow ("sky belt" in turkish) around here. Because of this people were afraid as in apocalypse and both jews and muslims and also other people from other religions went to their mosques, synagogues and churches and prayed in tears. Because of this situation lots of men and women were in panic, many pregnant women lost their babies, many children became epileptic. Cries had reached sky. After this meteor event the temperatures started to decrease, and weather started to get to normal. After a few days a meteorite weighing about 1.5 kg was found from the places that were hit by the falling objects and it was brought to the local government. This is presented to your high court for your information. June 27th, 1856, Kirkuk Post Office Manager.
