On Saturday morning, August 4, Marc and John were in Senegal with roughly 60 other observers from the US, France, and Senegal and Rodrigo was in Columbia with a dozen astronomers. Both groups were pursuing the shadow track of 2014MU69, the ~30km Kuiper Belt Object that New Horizons will fly be on New Years Day, January 1, 2019. Rodrigo’s teams in South America were rained out, and Senegal teams faced cloudy conditions. However, all teams persevered and several Senegal sites were clear enough to collect useable data. These data are currently being analyzed and synthesized with last summer’s campaigns to inform the New Horizons team as they plan for the upcoming flyby. We will provide updates as added details are made available.
In addition to collecting useful data, the expedition was a valuable opportunity for US and French observers to work with researchers from Senegal and to build international ties. The link above points to a New York Times article featuring the occultation expedition in Senegal.
