  We present a new family $\left\{ S_{n}(x;q)\right\} _{n\geq 0}$ of monic
polynomials in $x$, orthogonal with respect to a Sobolev-type inner product
related to the $q$-Hermite I orthogonal polynomials, involving a first-order
$q$-derivative on a mass-point $\alpha \in \mathbb{R}$ located out of the
corresponding orthogonality interval $[-1,1]$, for some fixed real number $q
\in (0, 1)$. We present connection formulas, and the annihilation operator for
this non-standard orthogonal polynomial family.
