On shift: AT, ER

  Still running at Ecm = 3470 MeV (chi0 background point).
  Pretty smooth shift. Beam energy apparently stable, unlike istantaneous
luminosity. Some problems with the Jet Target control and with the
Luminosity-Livetime window on main DAQ console. 
  Nozzle unclogging procedure performed right at the end of the shift.
After that, measured jet density gets much closer to setpoint. 
  For the sake of statistics: 12 DAQ hangs, all promptly reset.

  Run summary:

5460 (inherited):
  current: 22.4 mA -> 19.7 mA
  integrated luminosity: 308 nb^-1

5461:
  in progress

Final current = 17.1 mA
