While this sector has yet to be explored in our time, it will have been by SD 43.0825, when 5 Starfleet science officers will be abducted by unknown aliens, from the USS PEARSON in this sector and brought to what was for them the past. After being abducted Lt. Galia Bitzalel, Lt. T'Sara, Ens. Sarak, Ens. Ari ben-Avraham, and Ens. Setsuzo Kotsuji. They arrived on an unknown date, and were taken by the USS CURIE to SB Omega on SD 8.0910.1011 after the CURIE rescued them from the planet the aliens crashed on.
In the year 2411, site of the Intellidyne System's secret research facility. Built into a large asteroid, they were said to be doing research with a dimentional doorway. The new Manta Ray class support ship of DS 101 went to investigate on SD 11.0203.
Many years in the future, this will be converted into the starbase that Galia Bitzalel once helped to save from a Founder invasion, perhaps the dimentional doorway was involved? Only the future will tell.
