In addition to our meeting at IAU, Division F (our parent division) is hosting an event called Planet Days 2018 on August 24 and 27 during the General Assembly. The goal of this “pop-up” meeting is to allow for the IAU GA to cover brand-new topics that might not have been known about when proposals for meetings were due, such as Planet X and 1I/2017 U1 `Oumuamua.
Your registration for the General Assembly for our Focus Meeting will also allow you access to the Planet Days, so I encourage everyone to also consider submitting abstracts to this “pop-up” meeting and attending those talks and poster sessions.
