Space weather forecasts and nowcasts require rapid-cadence, continual, and robust solar observations. A useful strategy to accomplish this is to deploy a network of ground-based observing systems distributed in geographic longitude. The US Air Force Weather Agency (AFWA) has been operating the Solar Optical Observing Network (SOON) for many years, and is now replacing SOON with ISOON, an improved SOON. As a back-up during the development and installation of ISOON, AFWA is supporting the addition of an H-alpha observing system into the existing sites of the Global Oscillation Network Group (GONG) program. GONG comprises six sites in California, Hawaii, Australia, India, Spain, and Chile, and currently provides one per minute continual magnetic field, Doppler, and intensity measurements in the Ni 6768 line. The additional H-alpha capability will comprise a 0.4-A bandpass filter, a 2kX2k CCD, beamsplitter, transfer optics, and a dedicated data acquisition system. The observing cadence will be one per minute at a given site, with the acquisition time shifted between adjacent sites to potentially provide an image every 20 sec. The data will be transmitted back to Tucson, processed, and then transferred to AFWA within one minute of acquisition.
