First Results from a Deep Chandra Observation of the Hubble Deep Field North

Recent deep observations with Chandra have resolved over 75% of the 
2-10 keV X-ray Background (XRB) into discrete point sources, but the
nature of the objects contributing to the XRB still remains to be
determined.  This informal talk will describe one of the deepest  
Chandra observations so far:  the first 166 ks of an eventual ~500
ks observation of the Hubble Deep Field North (HDF-N) and its environs
(these data are part of the Guaranteed Time program of Prof. Gordon
Garmire).  The general X-ray properties of the sources and the
optical follow-up program will be described.  Additionally, there will
be discussion of the multiwavelength properties of the six X-ray
sources we have detected in the HDF-N and the X-ray upper limits we can
place on AGN candidates found in the HDF-N.
