Y Lyncis

Due to the New England winter storm currently affecting the area, phone coverage at the AAVSO may be much reduced until Wednesday. The staff is still available via email, and we suggest using that method to contact us if you need assistance.

Y Lyncis is an interesting semiregular of the SRc (supergiant) subclass with an obvious long secondary period.  While it has a primary pulsation period just over 100 days, there's a longer (and larger) periodicity over 1000 days.  Such behavior is common among this class of semiregulars, including the most prominent of the SRc stars, alpha Ori (Betelgeuse).

Y Lyn is bright enough for binoculars, and is a good target for northern hemisphere observers.
