Post annotation about this record

Note: Note that the errors on the proper motions are large (∼50mas/yr), and therefore the positions computed at an epoch different from 1991.25 have a large (∼0.4") uncertainty.
The Tycho Epoch Photometry data can be accessed from the morePhoto column (includes VT, BT and Hp photometric data for Hipparcos stars [filter responses]
