Sorry, I typed too soon about Kitt Peak CDD status. The CD shutter has failed, for reasons including quite a large moth lodged in the blades. Cleaning/lubrication didn't help; replacement is being sought. For now, the spectrograph and guider are available.

Live Astronomy @DragonCon 2023 - Dumbbell Nebula M27 in filter sets which are close to RGB, and using a narrow H-alpha filter for the red channel to emphasize the ionized gas. @SARA_Obs Kapteyn telescope, La Palma. @dconspacetrack

[William Keel @NGC3314]

Live Astronomy from @DragonCon 2023: after a panel talked about the captured planet in the globular cluster M4, it was too low, but we could reach its cluster cousin M22 in Sagittarius with @SARA_Obs JKT at La Palma. Red giants really stand out in brightness + color. BVR filters.

Live Astronomy @DragonCon Space Track: Pinwheel galaxy M101 and fading supernova (reddish star at lower left). Raced twilight and telescope limits at @SARA_Obs 1m JKT on La Palma. @dconspacetrack

[William Keel @NGC3314]

More from @DragonCon Live Astronomy - the ever-popular and striking Eagle Nebula M16 with its star-forming pillars of gas and dust, seen in H-alpha with the @SARA_Obs JKT on La Palma. @dconspacetrack

[William Keel @NGC3314]

Moving outward in @DragonCon Live Astronomy images - Jupiter, from Sunday night. Great Red Spot, Ganymede to upper left and Io below it. @SARA_Obs Kapteyn telescope, La Palma. Color a bit enhanced using wavelength baseline from U to H-alpha filters. @dconspacetrack

[William Keel @NGC3314]

Views from Live Astronomy sessions @DragonCon - landing site of Chandrayaan 3 (red circle) only a couple of hours before local sunset. U filter, @SARA_Obs Kapteyn telescope at La Palma. @dconspace

[William Keel @NGC3314]

Chilean telescope of @SARA_Obs is currently unreachable, as a result of actions taken by @NOAOSouth following cyber attack, presumably the same one which affected @GeminiObs . So much for the "wild west" days of the Internet being behind us.

[SARA_Obs @SARA_Obs]

Computer connected to this acct has been off for a while, so a lot of catching up happening.

Observers: malfunctioning ARC CCD at Kitt Peak has been replaced with twin once in Chile.

Going to site: AZ Hy 386 reopens to public to day, prepare for inexperienced mtn drivers.

[William Keel @NGC3314]

A colleague noticed this on the Kitt Peak all-sky webcam last night. This is why we unplug everything that has a plug @SARA_Obs for the monsoon season.

[William Keel @NGC3314]

Quick look between galaxy series from @SARA_Obs La Palma: #esaeuclid @ESA_Euclid continues toward L2, range 1.18 million km in these 1-minute exposures.

[William Keel @NGC3314]

Hey, La Palma telescopes are open after the wildfire! I can resume studies of EELRs and fading AGN with the @SARA_Obs Kapteyn telescope!

How do they know which galaxy I'm looking at?

[SARA_Obs @SARA_Obs]

We now expect this to apply also to our telescope at Kitt Peak for some time after scheduled reopening next week, as @NOIRLabAstro makes sure the attack is understood and a repeat is protected against.

Observatories on La Palma have been evacuated due to wildfire at Puntagorda to the west. Telescopes not in immediate danger, but staff is being cautious because there are few escape routes.

[Grantecan @GTCtelescope]

Finalmente se ha decidido evacuar el observatorio y dejar sólo los retenes mínimos en los telescopios.
