Spaceweather Storms
Coronal mass ejections (CME) provide hazards to the earth environment, in particular to satellites, and to power lines on ground.
Reliable spaceweather forecast required.

MuSTAnG
Muon Spaceweather Telescope for Anisotropies at Greifswald
Multi-directional muon telescope for spaceweather forecasting
Stage 1: 2 × 16 = 32 detectors of 0.25 m2 size each
Stage 2: Extensions to up to 2 × 36 = 72 detectors foreseen

Viewing directions
Viewing directions are defined by the passage of a single muon through one upper and one lower detector.

Integration of MuSTAnG into existing muon telscope network
MuSTAnG will be part of an international muon telescope network:
Nagoya (Japan) Hobart (Australia) Sao Martinho (Brazil) Bartol (USA)
