Well, here we are with another day done at the 233rd AAS meeting in Seattle.  There were a lot of good sessions today and several great plenary presentations.  I'm going to pick on one of the plenary sessions today dealing with X-ray astronomy.

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.

Greetings from Palmia Observatory


Well, we have been busy celebrating this Christmas season and holidays and the wind is really gusting now so not much sky observing at this time.  But, there is plenty of news to report.
