Query: Vanadium Transitions in the Spectrum of Arcturus   We derive a new abundance for vanadium in the bright, mildly metal-poor red
giant Arcturus. This star has an excellent high-resolution spectral atlas and
well-understood atmospheric parameters, and it displays a rich set of neutral
vanadium lines that are available for abundance extraction. We employ a newly
recorded set of laboratory FTS spectra to investigate any potential
discrepancies in previously reported V I log(gf) values near 900 nm. These new
spectra support our earlier laboratory transition data and the calibration
method utilized in that study. We then perform a synthetic spectrum analysis of
weak V I features in Arcturus, deriving log {\epsilon}(V) = 3.54 $\pm$ 0.01
({\sigma} = 0.04) from 55 lines. There are no significant abundance trends with
wavelength, line strength, or lower excitation energy.
