Shahab | Runs | data synch on WWW server |
Data is being shared on the WWW server.
Time difference between the analyzers is in order of seconds:
time stamp of the 245MHz data is leading those of 410MHz by 21.733 [s] |

Andrew Nic | Runs | Frequency shift |
The freqency suddenly shifted at time 16:11:47 and remained shifted until now
The ESR status in the monitor stayed blue. No obvious sign that a magnet was down. The operators are checking
Sergey telephoned, he is also not sure but suggests stopping starting the ESR. We will wait for Yuri |

IK, KK | Runs | drop of intensity |
We see a drop in beam intensity from 7E9 to 2E8 between 01:30 and 01:43 |

IK, KK | Runs | drop of intensity |
We see that intensity stabalized at 9E8 which is smaller then before.
We neticed this at 2:50, keep observing. |
