Education, Employment, and Maintenance of This Website
I received a BA in Astronomy and Physics and an MA in Astronomy from UCLA, and was working on a doctoral dissertation on the distribution of galaxies in the Universe (namely, they exist as individual galaxies, clusters of galaxies and superclusters) when I took a position as Long Beach City College's (at that time sole) astronomy instructor in June of 1970. I remained at LBCC on a full-time basis (and for many years, nearly a double full-time basis to accommodate increased enrollment) for 39 years. I retired from full-time teaching in May of 2009
, but continued to teach a reduced number of classes until May of 2012, at which time I fully retired after 42 years at the College. During that time I taught tens of thousands of students, and I greatly appreciate the notes some of them took the time to write, telling me what a difference my classes made in their lives. No matter what I may accomplish in later years, I expect my time at LBCC to remain the defining episode of my life.
My main astronomical activity at the moment (and I expect for the rest of my life) is the web site I maintain for students and the general public at cseligman.com
. As of February 2021 there were more than 1000 pages and 18000 astronomical images on the site, which are continually being added to and organized into an Online Astronomy Text
and Sky Atlas
, and are just as useful now as they were when I was using them for my classes, as evidenced by the fact that the site averages nearly a million visitors a year. I hope to have another 20 to 30 years to work on the site, and expect to eventually finish all the major projects associated with it; but whatever state it is in when I am no longer around, I have already made arrangements for it to remain online for as long as it remains useful and relevant.
Minor Note Concerning Address
Once I discovered how much I preferred teaching to research I abandoned my doctoral research, so although it might be appropriate to call me "Professor Seligman", "Doctor Seligman" is incorrect.

Past Astronomical Activities
Although as noted above I abandoned research soon after I started at LBCC, if you are interested in my early research, Google Scholar
lists a number of articles and citations of articles that I worked on as an undergraduate and graduate student at UCLA (the link is to the first search page for my name).
For most of my 42 years at LBCC I held Friday evening Astronomy Open Houses
about once a month throughout the school year, but now that I am retired I no longer present them.
