Scientific paper

We are in the final stages of establishing a three-site global network for continuous full disk H-alpha observations based on our experience with making high-resolution full disk H-alpha observations at Big Bear Solar Observatory. Utilizing existing telescopes at Big Bear Solar Observatory (USA), Kanzelhoehe Solar Observatory (Austria), and Yunnan Astronomical Observatory (China), the three stations are each equipped with 2K X 2K CCD detectors and will monitor the Sun at a 1 minute cadence. We expect to monitor the emergence of each new flux region to obtain an unbiased data set in order to understand why some regions grow to super-activity while most decay quickly, as well as a more complete and uniform set of flare observations. We also expect to implement automatic detection of filament eruptions. Having high cadence data from three observing stations will also increase the accuracy of solar rotation rates as determined by feature tracking techniques. We will show the first data sets from the new network.
