UPDATE – It looks like South Georgia has been spared a direct hit. Read a news update by the BBC here
DECEMBER 17 – A rather large chunk has broken off A68a iceberg as seen in the quick movie below.
DECEMBER 16 –

DECEMBER 15 – Another quick video below – this time showing 7 days movement. Will it now miss South Georgia?
DECEMBER 14 – Video below shows 6 weeks forward motion of giant iceberg A68a. Very soon we shall find out what happens next !
DECEMBER 12 – Perhaps a more southerly turn recently when playing the quick video below. Some observers now suggest the resting place for the giant iceberg could be on or near Clerke Rocks. Earlier indications it may head north could be wrong.
DECEMBER 9 – Video by the UK’s Royal Air Force (RAF) showing footage from its low-level reconnaissance flight over the giant iceberg, A68a. Approx 100km from VP/SG.
DECEMBER 8 – The world’s largest iceberg A68a, which broke off Antarctica‘s Larsen C ice shelf in 2017, is now 120km from South Georgia Island. Some observers suggest the “finger” of the iceberg may travel slightly northbound, perhaps in the direction of the ultimate and never before activated Shag Rocks AN-021. High resolution shots of A68a here.
DECEMBER 6 – The iceberg moved 20 km in 24 hrs. At this pace, it may “hit” South Georgia island in the next 3-4 days. However, even with today’s position, it’s hard to predict whether it’ll go north or south, but movement over the last days seems to indicate north. Worth watching if the “finger”might hit the continental shelf.
DECEMBER 4 – The iceberg continues its motion eastbound and is located ~100km from the extreme west tip of S. Georgia. Note the comparable sizes of both in picture above. Plus images taken by RAF cameras shown here.
DECEMBER 2 – Iceberg A68a has been imaged at high resolution for the first time in months – and it’s in a ragged condition. The world’s biggest berg is riven with cracks. Battered by waves and under constant attack from warm waters, it’s now shedding countless small blocks.

NOVEMBER 26 – Here’s a twitter update from the BBC’s Science Correspondent Jonathan Amos:
Iceberg Update: Last night’s @CopernicusEU #Sentine1a acquisition of the giant “ice finger” #A68 is in. What’s amazing is the flotilla of bergy bits leading the way towards South Georgia. I always measure the separation to Dulcoz Head on the island. Now 280km. @sentinel_hub pic.twitter.com/1Ci0vZQGR4

And the latest #Sentinel3 image. Remember, familiar behaviour should see the currents sweep the ice finger just to the south of the island and then spin it north. At some stage, the pointy digit has to snap… surely. pic.twitter.com/41dD3io5iP

NOVEMBER 21 – Edging ever closer to South Georgia, but will it take a different track soon?

NOVEMBER 15, 2020 – So it’s not really DX news, but still something for the DXer to keep an eye on especially as VP8/SG is always nice to contact. I mean, who could forget about VP8SGI for example?
You have maybe read about “A68 ” – a giant iceberg on collision course with South Georgia. I first became aware of the possible collision in a news article dated November 4th.
It’s now approx. 320 km away from South Georgia. The video below shows the movement of the iceberg over the last month. At the last minute it may avoid South Georgia, but for the moment I guess it’s something to watch unfold.
PS: Might it head towards South Sandwich instead?
It looks like it may hit SGI but it needs sustained strong SW wind and of course help from currents. But what about S. Sandwich islands? it's straight downwind and nothing in between to stop the berg, never underestimate the roaring 40s @CopernicusEU@BBCAmos @NASAEarth https://t.co/KAEh6E51u1 pic.twitter.com/zeA1ehXIK9
