Son: Dad, how do stars die? Dad: Drugs, usually.

What's another name for a supernova? A POPstar. HAHAHAHA. Living is pain. Unbearable. End me.

Also, no dark night any more (for a few months). Astronomers will be FRUSTRATED

Also, somebody would write a mobile phone app. You take a picture of the landscape, and
#betelgeuse would be in the sky. The app would tell you its astronomical magnitude, as measured by the brightness of the blue sky. IF YOU REALLY NEED TO KNOW!!Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
Come on guys - do you really care about its astronomical magnitude then!??? Let's just adore the ONCE IN A MILLENIUM view!

People wonder how visual (by-eye) observers would reliably estimate
#betelgeuse brightness when it goes supernova. It would be visible in daylight. Nothing to compare it with but the sun.Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
Aaargh! Of course
@ESO is the European Southern Observatory!

The Very Large Telescope by the European Space Agency
@ESO also observed#Betelgeuse. Will be able to determine if the star's radius expanded. Bigger star --> cooler surface temperature --> lower luminosity
. Or constant radius but instead a dust cloud in front?

If you own a digital camera with a tele lens, try taking pictures! Depending on your equipment, a tripod without tracking can be sufficient. The star dimmed quite a bit, but is still relatively bright

Stars in our 10 Star (Northern) Training Tutorial: 1. alpha Orionis a.k.a. Betelgeuse, a red star in the "arm pit" of Orion. WE KNOW THAT ONE!

You too can contribute! Check out https://www.aavso.org/10-star-training … The 10-Star Training Tutorials are designed for novices who have no prior experience observing variable stars. It is a walk through of how to find the star, how to make an estimate and how to submit the estimate to AAVSO

Error bars from AAVSO visual data are now much smaller than 100 days ago. Why? More data! Historically, only 0-3 observations were made per night. The dimming hype began in early December. Now, usually ~10 observations every night. Better for averaging, smaller uncertainties!

Now at 37% of my usual brightness!

My visual mag from last night was 1.60 (robust mean of 13 observations). That is 0.03 mag dimmer than the robust mean of the 5 previous nights (n=83, 0.8σ).

My visual mag from last night was 1.60 (med of 9 observations). That is 0.00 mag brighter than the med of the 5 previous nights (n=87, 0.0σ).
