eclipse.aas.org is Highly recommended!
Here is an announcement from Dr Richard Fienberg, press officer of the AAS. Just part of the press release. A link is provided for those wanting to know more.
The AAS has been hosting a set of conferences preparing for the eclipse. Local governments, police, community leaders, and others have been invited to the conferences to get information to help them prepare for the upcoming eclipse. These conferences have been highly successful in getting the word out in a correct way. One of the common requests at the conferences was to have a comprehensive web site and they have delivered. Great job folks!
