               For urgent assistance(a) 
               (e.g. intervention required, technical failure, 
               permission to open enclosure, etc.) 
                observers should contact the 
               Telescope Technician (TT) 
               via landline(s):
               
               
                  Non-urgent matters for the attention of technical staff 
               (including 
               TTs 
               and SAs), 
               should be addressed to:
               mh-techs@ucolick.org
                     (408) 238-0652 (120-inch Readout Room)
                  
                     (408) 238-4267 (Electronics Laboratory)
                  
               If 
               TT 
               is unresponsive, then telephone the 
               Support Astronomer (SA)  
               on-call corresponding to the initial 
               (E/J/P) 
               in the accompanying 
               calendar(b,k). 
               Note: 
               After midnight (Pacific Time), the 
               SA on-call 
               is associated with the preceding date (on which 
               the night began). 
               Exceptions are winter nights requiring Adaptive Optics 
               support(c).
 
                  Non-urgent matters for the attention of 
               SAs should be 
               addressed to:

                  Commonly, staff are alerted by incoming telephone calls, but 
               indisposed(d),
                              (e),
                              (f), 
               before automatic re-direction to voice 
               messaging(g).

               A response should be forthcoming within a few minutes. 
               The response may take the form of: 
               
               
                  
                     A staff member joining the Zoom video-conferencing 
                     session(h).
                  
                     An intervention within the (VNC) observing environment.
                  
                     A telephone call.
                  
                     An e-mail.
                  
               Persist: If no response is received within a few minutes,

            Notes:
         
            
            
               (a) Targets of Opportunity (ToO) are subject 
               to a dedicated 
               procedure.
            
               (b) Occasionally, more-than-one 
               SA 
               is on-call on a given date, to accommodate multiple 
               support requests, public events, etc. 
            
               (c) Adaptive Optics commitments (at Shane 
               Telescope) are denoted by LGS (Laser Guide Star) and NGS 
               (Natural Guide Star). If a time interval is specified, it 
               indicates  
               the SA 
               is on-call only for that interval (typically split at, or around, 
               midnight). 
               Commitments to public events are denoted by 
               MOS (Music of the Spheres), EWS (Evening with the Stars) & Tour.
            
               (d) Due to the distributed nature of the 
               Mount Hamilton facilities, staff may not always be immediately 
               available. 
            
               (e) Staff may be sleeping.
            
               (f) Mobile/wireless coverage around the 
               summit of Mount Hamilton and on Mount Hamilton Road is limited, 
               which may compromise or disable communications. 
            
               (g) The standard for University landlines is 
               to re-direct to voice messaging after ∼3 rings.
            
               (h) Observers are assumed to have knowledge 
               of the relevant Zoom video-conferencing sessions and 
               passcodes in advance.
            
               (i) Frequently, 
               SAs 
               may be physically present at the summit, even if not on-call.
            
               (j) Due to high volumes of unsolicited 
               calls disturbing the sleep of night shift workers, this 
               landline is automatically disabled at sunrise and 
               re-enabled several hours later.  
            
               (k) OFFMOC: Off-Mountain, On-Call.
              Occasionally, SA is obliged to be physically 
              off the mountain.
              SA is contactable primarily via mobile phone/SMS with 
              limited ability to respondent to calls as/when able.
              In such cases, contacting Telescope Technician(s) should 
              be observers' primary recourse.
