Radio star Posted By sheila on May 15, 2013 I’m going to be on the local radio: Onda Cero between 6 pm and 6:30 pm. I hope to post a link to it afterwards. Posted by sheila Sheila came to La Palma with a six month contract and has stayed 24 years so far. She used to work as a software engineer at the observatory, but now she's a writer and Starlight guide.
