I can track them because we have military-grade neutrino detectors, but it is still difficult.
It is the largest neutrino detector in the Northern hemisphere.

"I don't happen to have a neutrino detector on me at the moment," Garcia said, sarcastically.
I've got a call out for a mobile neutrino detector but the only one is in Japan.
Emerging on the far side, we tuned our neutrino detectors.
The operator's report confirmed the discovery made by the neutrino detector only minutes before.
As for knowing when a spacecraft is in the neighborhood, at a minimum there's our neutrino detector.
