Nostradamus c2 q41, a stab at an interpretation

The great star will burn for seven days,
The cloud will cause two suns to appear:
The big mastiff will howl all night
When the great pontiff will change country.

Cloud = the recently discovered interstellar magnetic cloud enveloping our solar system

Two Suns = the “Nemesis” hypothesis that we live in a binary star system, with one greater star (Sol) and another lesser star (Nemesis, a brown dwarf star a few times larger than Jupiter that orbits far outside Pluto’s orbit).

“The great star will burn for seven days”
Sol will be convulsed by a major sunstorm that lasts seven days

“The cloud will cause two suns to appear”
The effects of the cloud’s electromagnetic plasma will verify the existence of Nemesis.

“The big mastiff will howl all night”
England will suffer a long and terrible night

“When the great pontiff will change country.”
At the same time that the Pope abandons Italy

The quatrain makes it unclear if the unrest in England and Italy are caused by the arrival of the Cloud and the Two Suns, or if the only thing they have in common is the timing. However, it does seem that much of Europe may be in turmoil if such dramatic developments are occurring in both England and Italy at the same time.

Perhaps the mastiff is the destroyer flying through from a dog relate constellation/star...? I remember an anecdote about this event producing quick a bit of noise comes to mind.
Trumpets, thunders, etc

Hiya all!
