Visibility III / V
Jouko Markkanen, Ursa (Helsinki)
We set out to look for the Johnson comet, but it was still so low in the direction of light pollution (and plenty of moisture in the lower atmosphere) at the time of the observation that we couldn’t find it with 7x50 binoculars. Instead, close to the zenith, the Tuttle-Giacobini-Kresak in the Otava bucket was found quite effortlessly, although predictions predicted it to be dimmer than Johnson.
The picture shows a 90 second exposure with a 100mm lens. The battery had been forgotten to charge from the tracking device, so the stars no longer remained quite round, but the core of the comet is nicely visible.

En tiedä, mistä olet katsonut ennusteita, mutta ainakin Seiichi Yoshidan sivujen ennusteissa 41P/T-G-K on jo selvästi Johnsonia kirkkaampi. Myös havaintojen mukaan näin on.
