We report a multi-week sequence of B-band photometric measurements of the dwarf planet Eris using the Swift satellite. The use of an observatory in low-Earth orbit provides better temporal sampling than is available with a ground-based telescope. We find no compelling evidence for an unusually slow rotation period of multiple days, as has been suggested previously. A not, vert, similar1.08 day rotation period is marginally detected at a modest level of statistical confidence (~97%). Analysis of… CONTINUE READING
