Circumstellar Media and Late Stages of Massive Stellar Evolution

September 4-8, 2006, Ensenada, Baja California, Mexico

*****Sessions will start on Tuesday 5th******



The registration fee will be 50 $ (use cash for the fee at the registration desk). The registration will start on Monday the 4th of September at 18:00 at the Conference Hotel and will continue on Tuesday the 5th of September from 9:00 at the conference room.


It is recommended to arrive the 4th of September. Ensenada is full during that weekend because of "Labor Day" (USA vacation), and there will be probably no rooms available.

Single room 49 $.
Double room 69 $.
Family room (up to 6) 79 $.
Breakfast will be 6 $ per person.

Check in will start on Monday 4th at 1:00 PM at the front desk.
