Asteroids, meteors, and meteorites

Qr Bbpost Did you have one like this last year around this time too?

There was one in Sweden in November, which resulted in the recovery of a 14 kg iron meteorite.  This time it meteor was likely smaller, yet the airblast seems to have been stronger.

Qr Bbpost early Perseids?

No, Perseids are fast and disintegrate at high altitude.  This one came at about 15 km/s and faded low at 23.5 km altitude.  Also, it had an Aten type orbit mostly confined within Earth's orbit, which makes it quite rare.

Asteroids, meteors, and meteorites

Veeery busy day yesterday, complete media storm leaving little time to work out the meteor track. Meteor lights up the night in Norway Powerful air blast.  One fractured window reported, otherwise no serious damage.  I had just fallen asleep and didn't notice a thing, though my geophones in my basem...

Coronavirus (COVID-19) Thread

37056 China is one of very few countries that adopted what I would call a true "strike the curve down and keep it down" policy, in the sense that they were not content with having to deal with repeated waves. And they're hosting the Olympics in half a year.  I wonder how that will work ou...

Coronavirus (COVID-19) Thread

37041 when children are born do they inherit antibodies/immunity from their parents who had gotten sick from it? I'm not an expert but my understanding is that newborns have some protection due to antibodies shared through the placenta and then the breast milk.  So this protection is quite limited,...

Coronavirus (COVID-19) Thread

37031 But to blame a lack of data, the important question then is which data were lacking?  Like, how long various restrictions would be required (i.e. the effect on the spread and how exactly the pandemic would play out unchecked), and how much harm the restrictions would cause, for the economy an...

Coronavirus (COVID-19) Thread

37021 A powerful and well-researched piece by Tanner Greer on Palladium: I don't think what delays action is so much fear of panic, but lack of data.  The aid of hindsight makes this kind of criticism somewhat unfair.  And how most governments have dealt with this pandemic doesn't really strike me ...

Qr Bbpost I never get tired of it.

The only thing I might dislike about it, is that in winter if there isn't a lot of snow, such inversion might be bad for the snow conditions. It might be -10C or colder in the valley, but +5C above the clouds.

Qr Bbpost Mother of Pearl clouds!  Those are very rare- how often do you get to see them there?

A few times a year here, usually between December and February.  They typically form over the mountains.

Since I moved a bit uphill with a view many years ago, low clouds have been something which never fails to fascinate.  It can be really nice to look out of the window in the morning to discover that the city is gone and replaced by a white plain or desert changing every minute.  Here's a little coll...

36945 I actually thought space began where the exosphere merges with space, which would be around 600 miles or 1000 km up. There's no hard limit, but 100 km is often used, though this is way to low for an orbit.  Fast moving meteors will leave a glowing trail up to 120-130 km, so the atmosphere sti...

36897 By the way the Spacer era has now begun, Sir Richard Branson just launched into space! https://twitter.com/i/events/1414167242728644622 He reached an altitude of 53.5 miles. "Poor man's space".  Surely an awesome experience, but in my opinion, suborbital flights don't really count.

Actually,  I think we could keep all the CO2 on Mars if we could add enough nitrogen, oxygen and water to get at least the pressure we have on Earth.  But even though Mars is cold, such an atmosphere would eventually leak due to Mars' low gravity.

Floating cities of Venus is an old idea, and might not be a less far fetched idea than permanent bases on Mars.  In both cases the communities will be highly dependent on Earth for supplies.  Such settlements are basically space stations with extra challenges.  There is no "second Earth". ...

Unusual weather

It's going to be pretty hot on Sunday even at 66 degrees north in Norway.  The national record is 35.7C, which will probably stand, and the local record for this place is 35.0C.  This is the forecast for Mosjøen:
