Title

Light curve of T Cephei in 2020

About this image

This is my light curve for the Mira type variable T Cephei during 2020.

Although the period of T Cephei is usually quoted as 389 days, which would lead to maxima occurring 3-4 weeks later per year, maxima in recent years seem to have shown little change in their calendar dates.

The pre-maximum "plateau" also seems to have become increasingly prominent over the past decade.
