Spectral type O in 2023A&A...674A..26C not consistent with a T Tauri classification. Classified as giant in 2025MNRAS.537.1984A, consistent with the Gaia DR3 parallax. 2MASS colors indicate infrared excess typical of YSOs. Mean (likely) rotational period given in the table but the period varies in time between 3.5 and 3.9 d. Variations in other time scales also present. Short period variability with elements BJD 2459888.276 + 0.4810 x E in TESS data. Also a rather stable long period with elements BJD 2457309 + 178 x E, apparent in NSVS, ZTF, MQZ and ASAS-SN data. |

In the W3 star-forming region (2003AJ....126.1423K). J-K= 1.60; B-V= 1.67.
Mean magnitude change in NSVS data. Additional intrinsic variability superimposed to the main period. APASS magnitudes used for the comparison stars UCAC4 745-023164 (V:11.97) and UCAC4 745-023207 (V:12.70). |
