[BAA Comets] Two more on 1I/'Oumuamua

[Jeremy Shears]

APO Time Resolved Color Photometry of Highly-Elongated Interstellar Object 1I/'Oumuamua, https://arxiv.org/abs/1711.04927

...reporting no evidence of any cometary activity


Could 1I/'Oumuamua be macroscopic dark matter?, https://arxiv.org/abs/1711.04348

...suggesting it may be a chunk of dark matter, or "macro". This is a bit beyond my comprehension!


All the best,

Jeremy
