Lost lock at 09:57 (02:07) due to mag 5.8 Canadian earthquake. After things settled down enough to relock, had three lock losses at RESONANCE. The BS ISI tripped at the third lock loss, so decided to run an Initial Alignment (11:41 (04:41)). This went well, and required little hand adjustment. Started relocking at 12:07 (05:07). Reached NLN at 13:07 (06:07), and went into Observing at 13:08 (06:08) after clearing SUS TMS-X SDF Diff.
