I would like to announce an exciting new initiative aimed at the whole halo community.
For a long time, the Kern arc has been considered the “Holy Grail” of halos with only a handful of observations having been made and even fewer images captured. This year, I would like to invite all committed halo observers to really concentrate their energies on the area around the circumzenithal arc where the Kern arc appears. The aim is to try to photograph as many Kern arcs as possible this year, to better understand their frequency and to ascertain whether they really are the rarest of the rare. This initiative will go by the name of Project Kern.
I think that many more Kern arcs may potentially be photographed if observers routinely focus on this area of the sky. In the past, many Kern arcs may have been missed by observers concentrating their efforts too much on the activity occurring below the circumzenithal arc. In this endeavour, always try to use a tripod and take a series of images for later stacking. In this way, I hope that you will be able to capture several more of these elusive halos in 2017. I am sure that once more observers start actively hunting the Kern, more examples will follow as a matter of course.
I would very much like to encourage everyone to participate in this project and Halo Vault will be pleased to publish any Kern observation you might have the good fortune to make.
