Thunderstorm of the night of Perseids, pt. 2

It would have been enough for me to just see the thunderstorms of last night, but there was more to come! Last night (13.-14.8.2014) Mother Nature put up yet another wild thunderstorm show! I just thought that the previous night’s show was absolutely awesome! Wow, I’m totally speechless…

Thunderstorm of the night of Perseids

The night between 12th and 13th of August should have been a Perseid spectacle, but Moon and thunderstorms stole the show from Perseids. The thunderstoms of last night was easily one of the best thunderstoms shows that I have ever witnessed!

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!

The very first thunderstorm of summer 2013 happened during the Atmospheric Optics -meeting in the night between Saturday and Sunday. In the evening, Marja Wallin noticed, that it’s thundering and alarmed us! We went out to the observing platform to do some stormspotting! The storm started-up slowly, but the it got more intensive and it moved towards us! In this phase we observed also some mammatus clouds in the approaching cumulonimbus. Soon the night got very dark, and lightnings were flashing frequently! Ahead of the approaching cumulonimbus, we observed a shelf cloud. The shelf cloud approached slowly, but eventually it passed us, and the strong wind started to blow! Soon after that, it started raining heavily, and the storm was just above us! Then we observed many lightnings very near us, and some of them hit very close to us! After this, the storm receded, and then the thundering ended and it was just raining.
