  Though FM Del has been considered as a RR Lyr star by Preston et al. in 1959
(following discovery by Huth, 1957), Huth (1960) eventually changed his mind by
showing that it is in fact a cepheid of W Vir type of period of 3.95452 days.
Various authors since then have considered it as a cepheid indeed, with the
exception of Wils et al. (2006) who list this star in their RR Lyr catalog with
a period of 0.79688 days. On this basis, FM Del was added to Tarot RR Lyr
program. We present here these observations which confirm the cepheid type.
