I was observing the perseids -meteor shower in the night between 12th and 13th of August 2013 in Uittamo district of Turku, Finland. I was observing together with Linda Laakso, and together we observed in total 43 perseid meteors! Among the ordinary meteors, I was also able to see and photograph a really stunning perseid fireball, at least of magnitude -4!

Besides the meteor shower, we were able to observe some distant heat lightnings in the southern horizon. The lightning storm cell that caused the heat lightnings was somewhere over the Baltic sea in the south. The lightnings of this thunderstorm were flashing quite frequently, I was able to see lightning flashes in every one or two minutes!
