Query: SiO Maser Sources toward Globular Clusters   We report on the detection of SiO masers in Asymptotic Giant Branch variables
toward bulge/disk globular clusters. In five out of six cases, the radial
velocities are compatible with the optically measured radial velocities of
globular clusters in the assessed uncertainty. Two sources, toward Terzan~5 and
Terzan~12, lie very close to the cluster centers. The objects toward Pal~6 and
Terzan~12 have luminosities appropriate to the AGB tip in globular clusters,
while those toward NGC 6171, Pal~10, and Terzan~5 are brighter than expected.
It is suggested that the latter three may have evolved from merged binaries,
offering a test for binary-evolution scenarios in globular clusters, if the
membership is approved.
