VLBA Determination of the Distance to Nearby Star-forming Regions. VIII.
  The LkH$\alpha$ 101 cluster
  The LkH$\alpha$ 101 cluster takes its name from its more massive member, the
LkH$\alpha$ 101star, which is an $\sim15$ M$_\odot$ star whose true nature is
still unknown. The distance to the LkH$\alpha$ 101 cluster has been
controversial for the last few decades, with estimated values ranging from 160
to 800 pc. We have observed members and candidate members of the LkH$\alpha$
101 cluster with signs of magnetic activity, using the Very Long Baseline
Array, in order to measure their trigonometric parallax and, thus, obtain a
direct measurement of their distances. A young star member, LkH$\alpha$ 101 VLA
J043001.15+351724.6, was detected at four epochs as a single radio source. The
best fit to its displacement on the plane of the sky yields a distance of
535$\pm$29 pc. We argue that this is the distance to the LkH$\alpha$ 101
cluster.
