Hurray, I completed Micrometeorite Field Search #1070! It was conducted on a flat industrial roof outside of Oslo, where I live. The searching conditions were excellent; I collected 28 new micrometeorites even though it has only been two years since I last searched there.
The micrometeorites I acquired all have a size between 200 to 500 µm. Hopefully Jan and I will take some photos of the new ones on Tuesday.
