Hello, I am trying to find where to download human alpha satellite sequence. So far I have only been able to find one from 1987 paper: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC306152/pdf/nar00260-0438.pdf

I know that Karen H. Miga incorporated her Centromere Reference Models into GRCh38, so downloading her predicted sequences of centromeres would also be helpful - if you can point me where to download those. However, alpha satellite (or multiple since they are variable) would be the best.
Have you tried [RepBase](http://www.girinst.org/server/RepBase/index.php)?
