Russian support ship Nefrit is making a very slow steam along the coasts of Lithuania and Latvia.

The week before this she patrolled the perimeters of Kalingrad waters while the Baltic fleet held missile exercises.

IMO 9297773 She is nominally civilian. Image
Who called for cavalry? Nefrit is getting a Latvian Navy inspection by the looks of it. But both ships turned off their AIS 24 minutes ago. (I have sat access, coverage is good, other ships nearby get through even without sat.) Image

Russian conspicious supply ship Nefrit is continuing a slow steam along coasts of Baltic states. Slightly faster than previous 24h, but only at a fraction of normal speed.

Besides the Latvian navy inspection last evening a Swedish minesweeper passed within a km 01UTC. Image
Image
Image
Nefrit was also inspected by my favourite Baltic Sea ISR aircraft: Estonian 44 BLACK At noon UTC. Image
Image
A hypothesis of mine was that Nefrit is towing something secret. Nopes. Found matching echo on Sentinel1 sat images from this morning, nothing behind her. Sentinel2 from today is cloudy, but there is a hit and nothing behind.

@pmolpmol lists three ships interesting as suspected drone carriers in last night attack on Copenhagen Airport.

In this thread, I will argue that Russian ship ASTROL 1 is an excellent fit.

Right time, right type, erratic track just before attack, highly suspicious background. Image
Article that led me down this rabbit hole, by @pmolpmol nyheder.tv2.dk/live/krimi/202…
ASTROL 1 is a largely flat cargo ship with hatches that likely would serve well as drone pads.

She is a similar model to SCANLARK, recently apprehended by German authorities on drone suspicions and to PORT OLYA 4, drone import ship on Iran trade. Sunk by Ukraine. Image

Copenhagen Airport is closed for operations because of drones in the air.

Northern Europes most busy airport. Image

A Russian brand new fishing boat is almost blocking Öresund strait.

They seemingly lost propulsion 4 hours ago, drifted north towards the very narrow channels (~300m) but seem to have anchored.

Swedish coast guard and police have been at scene.

AIS-caveats apply.

Fishing boat in question is built this year 2025. Left St Petersburg about 3 days ago.

I thought I had found indications of a targeted GNSS jamming attack against president von der Leyen's aircraft this Sunday.

Then I disproved my own hypothesis. Here's how!

This is common for me, I usually don't show it because it takes a lot of effort to explain also 0-results
Hypothesis: if vdLeyen-flight was jammed by a directional jammer other aircraft in the emission cone would also be affected

I got the idea upon looking at an animation by @lemonodor

Marked flight began reporting bad GPS-values just as the pilot of vdL reported issues over radio Image
Animation I refer to available at this link: bsky.app/profile/lemono…

Swedish island Gotland is completely without power, for the second time in two weeks.

Gotland is considered paramount to NATO control of Baltic Sea.

As far as I know last outage is still being analyzed and cause is not known.

Power company now claims lightning strike as cause.

Article linked was updated.
