[Halo Reach] How did the UNSC not detect a covenant supercarrier arriving at Reach?

How did the UNSC not detect a covenant supercarrier exiting Slipspace over Reach then deploying at least two Corvettes and setting up the cloaking towers until after Noble Team investigated the communications relay that went offline?

I always assumed that the Supercarrier only arrived after the Spires and their cloaking field were established. The "dark zone" the Spires created hid the Solace's massive slipspace rupture.

In other words: Smaller, sneaky ships slip-spaced in stealthily to set up the sensor-scrambling Spires. The Solace slip-spaced in second.

(Try saying that ten times fast.)
