a symbiotic binary?

The ASAS-3 data of V1290 Aql looks like a Mira star
with a period of ~400 d. The maxima reach V=13.7.

Although this star has been classified as a symbiotic
variable, this supposed classification was based on
the initial classification (novalike variable) combined
with a late-type star.
The above observation is also consistent with my past
observations. Unless otherwise confirmed as a symbiotic
variable, the object may have been misclassified based
on various sources of fragmentary data.
