Meeting Time Change?

Josh/Randy

• Keep this meeting 1/week, move to coffee time?

• This meeting gets close to 100% attendance, coffee less so.

11:37

Keck 1 Restart

Randy

• K1 running for night ops this Thursday for engineering, science on Sunday

• Joel up tomorrow (Wed) night (closed dome tests?)

  • Gather ideas on this page.

• Jim developed engineering plan for first night

• ~1 hour of MOSFIRE checkout on Friday

• Sunday night’s science to be assigned. Probably split night UC and CIT.

• New laser, so SAs need training on checkout with new laser for LGS nights

• Schedule may slip

11:59

HQ/VSQ Use

Randy

• Email randy, hqserviceorders, vsq know if you need to go to HQ or VSQ

12:01

Observers

Randy

• Randy will email upcoming K1 observers and cc sas, mainland_observing

12:03

Recovering other instruments

Randy

• Want to get DEIMOS in beam by June 3 (is cold)

• K2 reconfigs at RNas can probably be done with social distancing. Still going through procedure. Likely can be done by one person.

• Move NIRSPEC to AO may be harder with social distancing. NIRSPEC to RNas probably doable.

• NIRES? Put on pump yesterday for a while. Some concern about poor vacuum, but should be ok if we pump it down. Telescope restrictions make pumping difficult. Plan is to have it cold in early June, science on June 12. Cool down takes 3 days.

• LRIS on schedule June 15. Cass reconfigs are biggest challenge for social distancing. Changing elements (gratings, filters, masks, etc.) can be done with one person. Needs ADC install as well.

• “Level 4” permits two person tasks as long as they are well planned and PPE is used.

• ESI is similar reconfig to LRIS, but needs tertiary removal as well.

• Need to alert observers to prepare masks. Elena emailed her LRIS observers for June, none needed MOS masks, just long slit. Elena will email other June LRIS observers.

12:17

PIG-less Instruments

Carlos

• What are guidelines? Jeff suggests using keywords. How to handle split nights?

• Change PROGNAME keyword, that governs KOA. Can still use two separate directories (OUTDIR), but that is optional.

• Observinglogs assume use of the second _B directory.

• OSIRIS does not use _B directory

• NIRES uses two different numbered accounts.

• Should we add PROGNAME functionality to existing PIG and observinglogs? This would be a big change for observinglogs.

• Can we use two numbered accounts in one night for DEIMOS? Not desirable to restart software (also painful for calibrations).

12:37

SSH key managements on instrument accounts

Carlos

• Conking in new DEIMOS system, what to do with SSH keys? How to handle when conking?

• Jim: Don’t conk .ssh directory.

12:44

SSC Agenda

Randy

• Agenda was sent out. SAs can connect as needed.

• Likely lots of COVID discussion.

12:46

June Engineering

Randy

• K1 engineering available in early June

12:47

Requirements for DRPs

Luca

• Marc asked SSCG for instrument requirements for software

• Several documents will be generated: DRPs, KOA, etc.

• This is first document: https://keckobservatory.atlassian.net/wiki/spaces/SSCG/pages/56295464

• Still figuring out approval path.

• SAs should review and comment.

Pau!
