HD+202466 14 Aquarii (abbreviated 14 Aqr) is red giant star. 14 Aquarii is the Flamsteed designation; it also bears the variable star designation IW Aquarii. It is a semiregular variable with an amplitude of a tenth of a magnitude, and shows variations on a timescale of just one day. At its brightest, magnitude 6.44,IW Aqr https://www.aavso.org/vsx/index.php?view=detail.top&oid=1085 The international Variable Star Index AAVSO 20 November 2024 it could be faintly visible to the naked eye under ideal observing conditions. In 1996 the variability of the brightness of 14 Aquarii was first detected, in the Hipparcos satellite data, resulting in the publication of its variable star designation in 1999.Kazarovets E. V.
