Mr. Thyssen worked out the solution in offlist emails with me.
I needed the -flatten option for the png background to be white.

Here is a copy of the solution:

You are right! Thanks. Upon testing, it is the -flatten option
that seems to do the trick for me.

convert  -density 288  lightcurve.eps  -resize 25%  -flatten lightcurve.png 

Thanks, I will post this to the original thread for the benefit of others.
