I am forwarding this request from Roy Axelson (ARX), for southern hemisphere observers to assist in a project observing delta Scuti stars.
"I have published several papers on time series DSLR photometry of southern delta Scuti stars in the JAAVSO in 2014 and 2015. Some of these involved Fourier analysis, with the data resulting in the inevitable one cycles per diay aliasing which is inevitable with photometry from one geographic site. I am seeking one or more collaborators in South America or South Africa, to observe the same target stars, to reduce the aliasing problem. I would be grateful if you could pass on this message to any likely observers on those two continents. My target stars to date have varied from 7th to 10th magnitude in V."
If you would like to help, you can contact Roy through the member contact form online or email directly to reaxelson at gmail dot com.
