Report

We travelled with Astro-Expeditions to observe this eclipse from the small French Polynesian atoll of Hikueru. Arriving on the atoll the day before the eclipse gave us time to find a suitable observation site, and polar-align the Vixen Super Polaris equatorial mount in the evening. From this remote spot in the Pacific Ocean light-pollution was non-existent and the night sky was incredible with the Milky Way stretching from Crux and Centaurus in the south, through Scorpius and Sagittarius, into Cygnus in the north.

Bands of cloud and light rain blew in from the north-east during the night and early on eclipse day. First contact was lost to cloud, but luckily totality was clear apart from a few seconds of thin cloud. More cloud covered the Sun during the post-totality partial phases.
