HD172829 is the reddest star on the Landolt Photometric
Standard Stars list: 110-353. This star is a strongly reddened K giant, and has been measured hundreds of times by several groups of observers, who have published V magnitudes very close to the lower end of the mag. range given here. The variable star name is based on old photographic estimates, and is almost certainly spurious. (Thanks to Brian Skiff for this assessment). |
