Preliminary constraints are placed on a cluster of YSOs (J2000 02:54:31.4
+69:20:32.5) discovered in the field of the classical Cepheid SU Cas. WISE 3.4,
4.6, 12, and 22 um images reveal that the cluster deviates from spherical
symmetry and exhibits an apparent diameter of 3x6'. SEDs constructed using
2MASS Ks (2.2 um) and WISE photometry indicate that 19 (36%) class I, 21 (40%)
class f, and 13 (25%) class II objects lie r<3' from the cluster center.
Conversely, 11 (18%) class I, 13 (21%) class f, and 37 (61%) class II objects
were detected for r>3'. Approximately 50% of the class I sources within r<3'
were classified solely using WISE photometry owing to the absence of detections
by 2MASS.
