|

**Re-estimation warning (2026-07-20):** T59 actual came in at 1.6x the estimate
|
||||
(381 vs ~240). Either billing is on wall-clock session time (Time Used matched
|
||||
start-to-end, not the 180 min of exposure) or the rate card's 80/hr for T59 is
|
||||
stale. Treat ALL queue estimates below as ~1.6x low until re-verified against
|
||||
account/history.aspx after the next paid run. At 1.6x, the remaining queue
|
||||
(~1,700 est) actually covers the full 2,257 balance nicely.
|
||||
**Rate correction (2026-07-21, supersedes the 2026-07-20 x1.6 warning).** Two
|
||||
paid runs now bracket the question, and both bill EXACTLY the plan's imaging
|
||||
minutes, not wall-clock:
|
||||
|
||||
| Scope | Plan imaging | Wall (Time Used) | Billed | Points per imaging hour |
|
||||
|---|---|---|---|---|
|
||||
| T59 | 180 min (36x300s) | 3h24m32s | 381 | **127** (0% moon) |
|
||||
| T32 | 120 min (24x300s) | 2h25m55s | 160 | **80** (25% moon) |
|
||||
|
||||
381 = 3.00 h x 127 and 160 = 2.00 h x 80, both to the point. So billing is on
|
||||
imaging time as originally documented, and the wall-clock theory is dead. What
|
||||
is wrong is the rate card in NOTES.md: it lists T59 at 80/hr (actual 127) and
|
||||
T32 at 146/hr (actual 80 even after the 25% moon discount, so a base near
|
||||
107/hr). The two look transposed, but two samples cannot prove that. **Do not
|
||||
apply a blanket multiplier.** Derive each scope's effective rate from its first
|
||||
actual bill, and treat any not-yet-observed scope's card rate as +/-60%.

### Session 2026-07-21 ~11:40 UTC (Cen A verify + cra-t8 booked)
|
||||
|
||||
Ran ahead of the 12:13 UTC scheduled job, after Cen A had finished at 11:16 UTC.
|
||||
|
||||
- **Cen A verified**: completed, billed 160, NGC5128 images on the scope server.
|
||||
Ledger and rate model updated (the x1.6 model is withdrawn: see the rate
|
||||
correction above).
|
||||
- **cra-t8 booked**, but on a better slot than the deferred option (b). Probing
|
||||
New.aspx for the original 01:35-04:35 returned "Conflicting reservation. Start
|
||||
time must be later than 2:25 AM" (hajo, as predicted), confirming that option
|
||||
(a) was all that remained on the night of 21 Jul, and it puts Corona Australis
|
||||
3.5-6.5 h past the meridian. Instead the run went to the EVENING of the next
|
||||
night: **2026-07-22T21:45 - 2026-07-23T00:45 SSO local**, which brackets the
|
||||
~22:30 culmination, so the whole 115 min of imaging happens near the zenith.
|
||||
This is option (c)'s geometry on option (b)'s night; the reason (c) was
|
||||
unbookable earlier (quota held by Cen A) had expired by the time Cen A
|
||||
completed. Grid probing showed no conflict on either side of the slot.
|
||||
Verified in Reservation/MySummary.aspx; quota now 6:50 / 8:00.
|
||||
- Moon on the night of 22 Jul is ~57% illuminated, the last usable night before
|
||||
the bright-week narrowband phase. LRGB on a dust complex under a half moon is
|
||||
a compromise, but the alternative is slipping a Phase 1 broadband target into
|
||||
the bright week, which is worse.
|
||||
- Reservation id NOT captured: the confirm response carries only
|
||||
`ModalStatic.result("OK")` and MySummary does not print ids. Nothing depends
|
||||
on the id unless the booking must be edited or deleted, in which case find it
|
||||
by probing Edit.aspx?id= around the current sequence (749314 was issued
|
||||
~08:55 UTC on 21 Jul).
|
||||
- Budget: 2,097 left, 19 nights to 10 Aug. Remaining queue at card rates is
|
||||
roughly 1,300, which UNDER-spends by ~800. With the x1.6 model withdrawn, the
|
||||
next planning session should add work rather than trim it: candidates are a
|
||||
second narrowband night on T59 (observed 127/hr, the only scope with a
|
||||
trustworthy rate), or extending the Phase 3 SMC and Tarantula runs, both of
|
||||
which have the sky time to absorb longer plans.
|
||||
|
||||
Substitution rules: if T71 returns to service, move #2 and #7 to T71 (faster
|
||||
f/2.8 optics, cheaper 106 pts/hr; re-cut the plans for 1.55"/px). If T70's

||||
server returns, book #7 as-is. Check the go.itelescope.net status line before

auto-start appears not to fire. If 749314 also fails to run, stop rebooking and

either walk it in (POST plan.asp per plans/README.md) or drop the free objective.
|

- CEN A verify pending: reservation 749302 (T32) runs 08:50-11:50 UTC 21 Jul.
|
||||
After 11:50 UTC, confirm images on t32.itelescope.net:8032, pull the actual

bill from Account/History.aspx, spot-check a preview, and refine the x1.6 rate
|

11:40 UTC 21 Jul: it starts 14:05 UTC. Verify after 14:50 UTC (images and logs
|
||||

|
||||
two prior free reservations (749228, 749229) expired unused with reschedule=No;

if 749314 also fails to run, stop rebooking and either walk it in (POST
|
||||

|
||||
- CrA on T8 runs 11:45-14:45 UTC 22 Jul. Verify after 14:45 UTC: images under
|
||||
/images/qisback/T8/ on t8.itelescope.net:8008, then the actual bill from
