Like many of you we in the GOTO collaboration have become concerned at the way X (we liked it better as Twitter) has developed, so we're leaving for Bluesky. Join us there as @GOTO-network.bsky.social

Our new (from 2023) site at Siding Spring, Australia has provided much more interesting wildlife than our original site at La Palma, in the Canary Is. Some native visitors are not as welcome and frankly a bit of a nuisance

Today's hybrid GOTO collaboration science meeting (in-person at @WarwickAstro) showcases an amazing year for our project. Both nodes are operational and regularly detecting transients from a wide range of triggers. Plot from David O'Neill's talk; TNS = Transient Name Server
Slide from the talk of David O'Neill (Warwick U.) showing the performance of the GOTO Network over time, and comparing the stats for transients streamed, reported, and leading to new discoveries from August 2023 & 2024

Our GOTO instruments now have a smaller sibling... introducing "Gotito"! It's a single ASA unit telescope on a mount on La Palma that @WarwickAstro PhD student Ben Godson and other collaboration members will use as a test platform for possible future camera and filter changes.

We also plan to use Gotito for confirming new detections from the larger array during the night, and performance will be similar. Currently fitted with Sloan g, r, i and Bessel I filters in addition to GOTO-L so beautiful colour images like this snap of M31 are also possible

Collaboration members from @MonashAstro and @WarwickAstro are at GOTO-South this week to replace cameras following maintenance. K. Ulaczyk took this magnificent image showing the Great Celestial Emu, as known by indigenous observers of the sky, head down theguardian.com/commentisfre…

Not all the wildlife on site is as appealing... this ferocious-looking female Red-headed Mouse spider can produce copious amounts of a highly toxic venom, which is potentially as dangerous as that of the Sydney Funnel-web Spider.

With interferometric detectors on hiatus, we have no chance of binary neutron-star inspiral detections for a while. We're still following up GRB triggers, but what else do our followers think we should observe?

The first half of our fourth observing run (O4a) has come to a close We'll be back with an engineering run on 13 March, and should start the second half of the observing run (O4b) on 27 March observing.docs.ligo.org/plan… Please no-one explode until we're back!
Planned timeline of observing runs. The fourth observing run has two halves, each of about 9 months

.@MonashAstro's Felipe Jiménez-Ibarra presented this week on black holes and GOTO to high school final year students at IES Santa Úrsula, Tenerife (Spain). More than 80 attendees, including students and teachers, particularly excited about our kilonova-seekers.org project!

A huge milestone for newly-commissioned GOTO-South yesterday: first science output! Our GRB working group reported very early non-detections of GRB 230911C around 5 mins post-trigger, read more here: gcn.nasa.gov/circulars/34662
