We recently launched a brand new version of the MyNewsFlash. This new version is recoded 100% from scratch and fixes many bugs and annoyances that plagued the older version. It also has some nice new features such as links that take you to the light curve of the object with that data point highlighted, lists of the affiliations of observers that contributed data, comments for each data point, etc. The signup page also has more options, such as the ability to only include observations made using specific equipment.
The AAVSO offers several methods of getting the news out that your favorite star has been observed, or something odd and interesting is going on in the sky.
MyNewsFlash allows you to set up a method of emailing or texting you the activity of your favorite star, or class of stars. You can see what your star's current behavior is, based on current observations, and plan your science sessions accordingly. You can create your profiles for MyNewsFlash by clicking on the link above.
