• Vacuum conditioning (outgassing by SR) was carried out with beam currents of 450-500 mA.
• Betatron tune was adjusted. As the result, beam lifetime was improved when undulator/wiggler gaps were changed.
• Superconducting vertical wiggler (VW#14) was excited to 4.8 Tesla in the evening.
• We had an earthquake at 11:13 PM, but there was no damage.
• An integrated current of 10.7 A*hrs was gained from 9:08 AM (Oct. 19) and 9:06 AM (Oct. 20). Average beam current was 447 mA during this 24-hours.

Beam current and beam lifetime from 9:00 AM Oct. 20 to 9:00AM Oct. 21.
Vacuum conditioning and machine tuning were carried out.
