Overall status: In A configuration (ending 12 Sep); Correlator hardware (usually 59 BlB pairs) available; some troubling issues with boards; some troubling issues with CC.
Key dates:
08 Jun - 12 Sep: A configuration (move from 31 May - 08 Jun).
Staff Travel:
FO: 12 Aug - 12 Sep
RP: 10 Sep - 16 Sep (Brazil)
Visitors:
Michiel Brentjens: 11 Jun - 11 Nov (Holography; characterizing polarized beams)
Hardware status and updates (Langley, Perley, Rupen)
Array (Perley/Langley):
Antennas:EA23 back to the array this week. EA25 out.
Receivers: EA24 for first L-band solar capable Rx; several more weeks for this.
Perley: RF Switch testing ongoing.
Calibration (Perley): Gain compression/expansion ongoing (Hayward).
WIDAR (Rupen):
Notes (Rupen/Sowinski): Currently 59 BlB pairs ready; some issues from the weekend: board loses communication; specific CCC's begin blocking frames; missing scans (single example to be explored).
NOTE: Please cc me on submitted tests so that it can be assigned the appropriate priority!

Issues Affecting Science Observing:
Correlator: [Rupen/Carlson w/ Momjian/Sault] V stokes issues.Following showing consistent issues; work this week using phased array.
Correlator: [Pokorny/Rupen/McMullin] time mislabeling in SDM data (non-synchronous operation between correlator dumps and CBE can require additional 1/2 integration time padding for online flags). .Needs close-out testing (Michael-update activation time testing).
Correlator: [Clark/Carlson] Delay rocking across bands. (October)
Array: [All] Zoo of other effects (some data are very good, some still seeing antenna-based IF/Polarization issue).
Testing This week/soon
[Sowinski et al]; Executor update testing
Phased array testing (Thursday+)
Planetary tracking tests
[Owen]: L band deep field study
Subarrays: cleanup.
Stage 2 mixer testing to relax sub 128 MHz BW grids
Correlator: Rupen: S-band shadow testing
Spectral line: Roy/Dhawan: HI High resolution bandpass testing
