11807 Wannberg

“Asta Pellinen-Wannberg was the first scientist in the world to use big scatter radar to study meteors, triggered by small particles from space, penetrating the atmosphere. Together with Gudmund Wannberg, then, Technical Manager and Deputy Director of the EISCAT radar facility, as well as Teacher at Umeå University, they discovered by accident in December 1990 that meteors could be systematically studied with the EISCAT radar. This work is now rewarded and it is nice that the asteroid is wearing the pioneers’ common surname. – forskingn.se (latest 2017-05-09)
