  The Belle II detector at the SuperKEKB accelerator observed the first
collisions in April this year. Until mid-summer, the first commissioning run
uses a reduced version of the full vertex detector. Nevertheless, this phase is
an excellent opportunity to improve and test the alignment and calibration
procedures being prepared for the first physics runs starting in spring 2019.
  The procedure presented is based on Millepede II tool to solve the large
minimization problem emerging in the track-based alignment and calibration of
the pixel and strip detectors, the drift chamber or the muon system. The first
alignment of the vertex detector was performed quickly after the first
collisions and further improvements are expected with more data and with
inclusion of other sub-detectors into the procedure.
  This contribution will show overview and status of the Millepede alignment
and calibration procedure of the Belle 2 sub-detectors, after first collisions
and the plans for full physics run.
