$\begingroup$ The website from the American Association of Variable Star Observers has info about the magnitude variations of Betelgeuse in its "Star of the Month" article.

Betelgeuse keeps getting dimmer, diminishes to 1.506 magnitudes. Betelgeuse is classified as a semi-regular variable star. The star currently hovers around magnitude +0.42. It marks the upper left-hand corner of the ancient hunter figure. However, this particular fading has proven to be most unusual. Betelgeuse is a red supergiant star in the constellation Orion. The star will go supernova at the end of its life, but that’s not projected to happen for tens of thousands of years or so. Betelgeuse was, indeed, noticeably fainter, about a shade dimmer than nearby +1 magnitude Aldebaran.
Betelgeuse, second brightest star in the constellation Orion, marking the eastern shoulder of the hunter. It has a variable apparent magnitude of about 0.6 and is one of the most luminous stars in the night sky. Stars emit a huge number of neutrinos as they die, and this emission increases in intensity as the star gets closer to explosion.

$\endgroup$ – … The symbol for apparent magnitude is a lower case m; you must make this clear in any problem.. Absolute Magnitude, M What does the fact that Sirius has an apparent magnitude of -1.44 and Betelgeuse an apparent magnitude of 0.45 tell us about these two stars? But observations made this month by both amateurs and professionals indicate a steep drop in brightness. Betelgeuse continues to dim, diminishes to 1.506 magnitude.

The star’s mass is uncertain, but estimates range from 7.7 to 20 times that of the Sun. That’s 20% dimmer than the “modern all-time low” registered last month. Betelgeuse is a red supergiant star in the constellation Orion. Betelgeuse is one of the largest stars currently known — with a radius around 1400 times larger than the Sun’s in the millimeter continuum. by Evan Gough, Universe Today. But recent estimates have shown that it has faded to around magnitude +1.7, dropping it out of the “Top 21.” As such, Betelgeuse has become exceptionally dim. The star will go supernova at … It has an absolute magnitude of roughly -6.02. Bellatrix (gamma Ori) is about 5° west of Betelgeuse in the constellation Orion. The "average" apparent magnitude is 0.58, but it can vary between 0.3 and 1.2.

It’s Down to 1.506 Magnitude. Betelgeuse keeps getting dimmer, diminishes to 1.506 magnitudes.

Its apparent magnitude varies from 0.2 to 1.2 over a period of about 400 days, which is the widest magnitude range for a first magnitude star. Red Aldebaran is almost the same height above the horizon as red Betelgeuse, making comparison easy. Astronomy Meta your communities . Betelgeuse can be found approximately 643 light-years away, on the shoulder of Orion, the Hunter. Astronomy help chat. If you check the list of the brightest nighttime stars, Betelgeuse ranks 10th.

“The most recent measurements put the visual magnitude of Betelgeuse at about +1.66, the dimmest its been in our 25 years of photometry,” says Edward Guinan of Villanova University. About 600 light-years away in the constellation of Orion (The Hunter), the red supergiant burns brightly, causing it to have only a short life expectancy. current community. Little did they know when they issued their telegram in December that Betelgeuse was about to become even fainter. Betelgeuse is well-known because of its bright size and easy-to-spot location in the constellation Orion. Betelgeuse keeps getting dimmer, diminishes to 1.506 magnitudes. Betelgeuse is a red supergiant in Orion that's one of the most famous stars in the sky.

Magnitude estimates of Betelgeuse, going back to 1970. Credit: The AAVSO. But that’s only an average: the variable star's brightness typically varies from magnitude 0.2 (roughly like Rigel in Orion's knee) to about 1.3, only a few tenths of magnitude brighter than neighboring Bellatrix (magnitude 1.6). Normally, Betelgeuse shines at a magnitude of +0.69, ranking it as 11th among the 21 brightest stars in the sky. Betelgeuse is a red supergiant star in the constellation Orion. A red supergiant star roughly 950 times as large as the Sun, Betelgeuse is one of the largest stars known.
