Optical spectra of SN1993J in M81 are presented for each night from \mbox{March 31.1 1993 UT} to \mbox{April 7.1 1993 UT} with wavelength coverage from \mbox{4400 $\rm\AA$} to \mbox{8200 $\rm\AA$} at \mbox{4 $\rm\AA$} resolution. Emission features near 4950, 5860, and \mbox{6560 $\rm\AA$} begin to appear on March 31.1 and continue to rise throughout the first week. Faint emission near \mbox{6370 $\rm\AA$}, probably due to \mbox{[Fe X] 6374 $\rm\AA$}, is detected on \mbox{April 1.1} and fades by \mbox{April 2.2}. This fading suggests a radius of 0.001 pc for the [Fe X] emitting region, assuming a SN expansion velocity of \mbox{10,000 km s$^{-1}$.} The H$\alpha$ feature at 6560 $\rm\AA$ extends from 6350 to 6800 $\rm\AA$ corresponding to velocities of \mbox{$\rm\pm$ 10,000 km s$^{-1}$.} A slight dip centered at \mbox{6516 $\rm\AA$} is seen on the H$\alpha$ emission peak beginning \mbox{April 2.2}, and grows deeper through the first week. If the feature at \mbox{5860 $\rm\AA$} is due to \mbox{He I} $\rm5876\AA$, the corresponding Doppler width is \mbox{$\rm\pm$ 12,000 km s$^{-1}$.} Possible absorption features blueward of H$\alpha$ and \mbox{He I} appear on \mbox{April 3.1}, as well as emission near \mbox{ 5100 $\rm\AA$}. On April 4.1 the feature at \mbox{4950 $\rm\AA$} resolves into two peaks at 4797 and \mbox{4909 $\rm\AA$}, which we attribute to blueshifted \mbox{Fe II} 4924, \mbox{5018 $\rm\AA$} lines. On April 5.1, the emission at \mbox{5100 $\rm\AA$} can be resolved into two peaks centered at \mbox{5073 $\rm\AA$} and \mbox{5226 $\rm\AA$.} Discussion of these data will be presented.
