    It's slimmed down a bit (down from ~5,800km2 to ~5,000km2) but is basically still intact following its departure from the Larsen C Ice Shelf. Once in open water, there's got to be a good chance it will fracture.

    So I know everyone's got their eyes on Pine Island Glacier because a biggish calving is imminent, but keep some of your gaze on . It really is motoring. Now poking above 63 degrees S and about to break free of surrounding sea-ice.

    Not much new coming out of this meeting. Two soon-to-published studies presented. One from modelling how much large telescopes could be impacted; the other from that considers what's shiny on the Starlinks, eg solar arrays.

    And this. Eddington's photographic plate of the 29 May 1919 total solar eclipse that essentially told us that Mr Einstein's musings on general relativity were bang on. Amazing to witness these historic artefacts.

    So, you think the "first light" images of the Sun from the Daniel K Inouye Solar Telescope were cool. How about these? Just hanging out at the (as you do) and here is Carrington's drawing of the sunspot group that yielded his famous flare "event" in 1859.
