233rd AAS Meeting in Seattle; Wind Direction on rotating Earth; Naming of Oumuaamua and comparison with New Horizon's MU69; Black Hole formation rate; Obscured galaxy spectral measurement; Time out for a martini

Greetings from Palmia Observatory


Well this week we are in Seattle for the 233rd American Astronomical Society (AAS) Meeting.  It is about 10 degrees colder than southern California and it has a light rain periodically.  Luckily, it is just a 2 minute walk, only about 1/2 minute, outside in the weather from the hotel to the conference center.
