Asteroid (12171) Johannink
Asteroid (12171) Johannink = 2382 T-3 = 1998 HC45 = T/2382 T-3
was discovered at Palomar on 1977-10-16 by C. J. van Houten, I. van Houten-Groeneveld and T. Gehrels.
The name of the asteroid was suggested by K. Miskotte. Carl F. Johannink (* 1959) is a Dutch high-school teacher and amateur astronomer. His main interests lie in meteor astronomy. He is a very prolific meteor observer, active within the Dutch Meteor Society.
In order to demonstrate the performance of the Faulkes Telescopes, we accepted a proposal from our Dutch partners to take asteroid Johannink with the 2-meter Faulkes Telescope South in Siding Spring/Australia on March 28 and 29, 2020: one image each with an exposure time of 180 Seconds, red filter and automatic dark, bias and flat correction.
