ACKNOWLEDGMENTS: The idea of operating a S.I.D. monitor first came to my mind about a year ago, intrigued by AAVSO solar bulletin’s SID events. Stanford and S.A.R.A. made it possible by providing the SuperSID receiver and the software.  It never occurred to me however to publish the daily data to my web site. Dimitris, a colleague and excellent developer, dropped the idea and offered to assist with his expertise. The software needed to  upload solar graphs at the top of the page are his creations.  All I can say is a big THANK U
