Query: The LkHa 101 Cluster   In the infrared, the heavily reddened LkH$\alpha$ 101 is one of the brightest
young stars in the sky. Situated just north of the Taurus-Auriga complex in the
L1482 dark cloud, it appears to be an early B-type star that has been
serendipitously exposed during a rarely observed stage of early evolution,
revealing a remarkable spectrum and a directly-imaged circumstellar disk. While
detailed studies of this star and its circumstellar environment have become
increasingly sophisticated in the 50 years since Herbig (1956) first pointed it
out, the true nature of the object still remains a mystery. Recent work has
renewed focus on the young cluster of stars surrounding LkH$\alpha$ 101, and
what it can tell us about the enigmatic source at its center (e.g., massive
star formation timescales, clustered formation mechanisms). This latter effort
certainly deserves more intensive study. We describe the current knowledge of
this region and point out interesting work that could be done in the future.
