APPARENT PLACE

Where a telescope has to be pointed today, which is not quite where the catalogue records the object: the coordinate grid itself has turned since the year 2000 the catalogue is referred to.

GRID TURNED SINCE

PROPER MOTION SINCE
1.05

Computed for 2026-08-27 00:00 UT. Two things separate it from the catalogued position above: V4074 Sgr has moved under its own proper motion, and the coordinate grid has turned under it — about fifty arcseconds a year of precession since 2000, and the small nodding of the Earth’s axis on top of that. Aberration and refraction are not included, and neither is parallax; each is under an arcminute, which is also about as well as the catalogued position is known. The same figure for any date.

VARIABILITY

] Z ANDROMEDAE SYMBIOTIC VARIABLE
RANGE, AS SAMPLED
11.34 – 11.67

No period is published for this star, so there is no cycle to count. The catalogue records that it varies and by how much, and not how often.

The range is the spread the Hipparcos satellite measured, converted to the visual scale. It is approximate: the satellite sampled the star on a schedule of its own, and where a star spends little of its cycle at an extreme — the floor of an eclipse, most obviously — the sampling can miss it altogether. The classification is the General Catalogue of Variable Stars’s. These elements as data.

Each link carries the identifier printed beside it. Nothing on this page is a measurement of our own, so a number that disagrees with one of these is worth reporting — and a service that has never catalogued this object under this name will say so plainly.
