Since the ops center power outage noted in the blog ops center power was off, the power has gone out three times two evenings ago and at least twice last evening.  Each time it's the main breaker that has tripped and must be reset, and (afaik) always in the evening with the overhead fluorescent lights on. Power will stay on for around 30 minutes before tripping again.  Yesterday I think the overhead lights were on all day, but the power didn't go out until the evening.  Someone please correct me where this report is wrong.

• Seems like we should report this problem to the person responsible for the ops center and see if they can get an electrician to investigate the problem.  Maybe the main breaker needs to be replaced or upgraded.
