Science Ops

• May need to discuss extension for Sunrise co-observing.

• PSPE21 on 9/30. This is a Cryo-NIRSP observation only.

• October 1: Solar Orbiter co-observing: R_BOTH_HRES_HCAD_Filament_Prominence - high-resolution observations of prominence at West limb, close to Earth quadrature (~4hrs) - pVSTP - FOR DKIST: on-disk filament observation SOOP Coordinators: T. Kucera, S. Parenti

• October 2 - 19: different co-observing programs: AR Long Term (multiple days - may not be consecutive), SMALL_MRES_MCAD_Earth-Quadrature - high-resolution observations of target at West limb, close to Earth quadrature (~2hrs) - pVSTP SOOP Coordinator: P. Chitta, SMALL_HRES_HCAD_RS-burst 30 mins of EUI super high cadence observations - pVSTP Moved to 19 October during DKIST-available time (1800-2200 hrs, depending on when best fits the SPICE observations for Fast Wind).

• Need to continue with FIDO 3a AND 3c experiments. Configuration for Solar Orbiter should be 3c - need for FIDO changes of CL2a position - hot swap testing FIDO-150.

• Support on two saturdays instead of sundays.

• Other science operations priorities:

  • Experiment generation for Cycle 3 start: ideally we need to know at that point what DL modes to include.

  • Cycle 4 Proposal Call preparation in full swing.

  • Testing of Cycle 4 configurations? We did not want to offer untested configurations anymore.

  • Rolling shutter for ViSP: increase of operational efficiency (no more NDs) and increased frame rate at same exposure time at the cost of lower SNRs and exposure time testing starting from scratch.

  • DL-NIRSP SV with Cycle 2 experiments continued → visible camera needs to be implemented, focused (float?) → required for Cycle 4 preparation, need to know what to offer.

  • Testing of 50/50 and 70/30 BS.

  • ViSP modulator replacement: beam wobble mitigation.

  • Step one in prep for ViSP beam attenuators: put the mounts in.

Technical Ops

• OCP2.9

  • surplus material disposal and Haz material storage org and inventory

  • baseyard packing of plate coil boxes into Containers and reorg of baseyard.

  • Site EV Charger (x2) installation.

  • Main UPS servicing & repair (S&B and first day of ops ) - small risk to obs.

  • ongoing con-current maintenance.

• Eng 2024E (& 2025A)

  • VTF support etech/ mtech / ME & EE.

  • Removal (and replacement) of the Enclosure Cable Wrap Hoses for TMW and HW. 3 to 4 weeks of non movement on the enclosure. Can be broken into parts ie one hose at a time.

  • Annual Electrical Distribution System Panel Maintenance - site wide electrical outage approx 4 days provisional plan Wed 1/8 to Sat 1/11 with Sun 1/12 as contingency and system restart on Mon 1/13.

  • Upgrade of PESDs for voltage absence and voltage presence detection on main system drive disconnects.

  • UB Electrical Tie-In for Solar Panels - site outage for 2 days.

  • Enclosure Az Drive tuning with Siemens Tech on site - 1 week

  • CDU server Room switch over for Row A & B ???? - 3 to 4 weeks no cooling - unlikely.

  • Coude LIC Refurbish - 2 weeks with no motion & permanent estop.

Instrumentation Ops

• InstOps needs two/three weeks to warm Cryo-NIRSP, open to install new resolvers, and cool down.

  • Plan was for 2025/Q1 (January), assuming there is 3 weeks of engineering

  • Other CN work: leak checks, cold-head duty cycle, new slit masks, broken filter holders, 2nd grating base, replacement of grating harmonic drive.

• InstOps would like to install MCAO 4km DM table and M9b table.

  • Arrival of tables by November will be possible but challenging. January would be ok but would overcommit InstOps for work this month (working along with CN, MISI-116).

  • This keeps the MCAO and M9b work on schedule for initial frame installation in winter 2025/26.

  • Would require crane, opening of floor, realignment of M9a onto new table.

• Potential MISI-116 installation

  • November not possible, January may be possible.

  • Still lots of smaller parts to be built, including several moving mechanisms.

  • Next opportunity for installation may be winter 2025/26.

• Numerous smaller tasks to be done in either Nov or Jan engineering period

  • ViSP filter holders. ViSP beam-balancing optics and testing.

  • More GOS cover work, depending upon repairs in July and Sep.

  • Optics as-built metrology.

  • DL-NIRSP modulator cooling.

  • Potential removal and shipment of VTF cameras for single-gain upgrade.

  • Discuss possibility for further vibration campaign work during winter shutdown.

• HLS

  • Upgrade to Java 17. Extensively test all instruments and systems by executing observations.

  • Install and test tgz data accumulation for Data Center Globus transport.

  • Upgrade login security.

  • Potentially move engineering data storage services to Amazon Web Services

Data Center

• Finish Cryo-NIRSP pipeline acceptance and begin Processing Cryo-NIRSP backlog

• Finish DL-NIRSP Beta Pipeline and begin acceptance cycle(s)

• Move all quicklook movies to Vimeo - For Back-up and bandwidth savings

• Upgrade the Ceph cluster to the “Pacific” revision

• OT - Implement Globus Accounting changes

• OT - Design Experiment Architect templating solution
