\begin{abstract}

We report the detection of a new radio transient source, \src, located
only 1\fdg1 north of the Galactic center.  Consistent with other radio
transients toward the Galactic center, this source brightened and
faded on a time scale of a few months.  No X-ray counterpart was
detected.  We also report new 0.33~GHz measurements of the radio
counterpart to the X-ray transient source, \xtesrc, previously
detected and monitored at higher radio frequencies.  We show that the
spectrum of \xtesrc\ steepened considerably during a period of a few
months after its peak.  We also discuss the need for a more efficient
means of
finding additional radio transients.
