Sažetak
The Croatian Meteor Network Catalogue of Orbits for 2007 contains 1211 orbits, out of which 358 belong to previously known streams. The radiant analysis pointed to a possible new stream with radiant in Cassiopeia, at $\alpha=6\dg9$, $\delta=50\dg7$ and $v_g=57.3$ km/s. The maximum activity is around solar longitude of $113\dg2$. This stream was assigned IAU shower number 444 and three-letter code ZCS. The proposed name of the shower is Zeta Cassiopeiids. The analysis of data for the following years (2008--2011) shows that the meteors belonging to the new stream were present in each year.
