Praesepae, Moon, Comet and the Solar Corona
This image illustrates excellent observing conditions in Klyuchi during the total solar eclipse. It
is possible to identify at least 137 stars including the open cluster M 44 Praesepae (NGC 2632),
which is visible in the bottom right image corner. The sungrazing comet
C/2008 O1 (SOHO) is a very interesting object which is visible in the lower part of the
image. The comet belongs to the Kreutz family. The comet was found not only on images taken from
Klyuchi but also on images taken by the second part of our expedition in Mongolia. See
this page for more information.
