Beltegeuse could become a supernova by February 21.

The star Betelgeuse will reveal likelihood to go supernova by Feb 21st

This whole episode might just be a deeper-than-average pulsation, and perhaps the supernova watch can be called off. However, notes Guinan, “even if the 430-day period is still working, this would indicate a minimum brightness near 0.9 mag–much brighter than the current value near 1.6 mag. So something very unusual is going on.”


I'm putting this here but I don't know if it belongs better elsewhere.

He talks about AD Leonis having a confirmed flare uptick

AD Leonis (Gliese 388) is a red dwarf star. It is located relatively near the Sun, at a distance of about 16 light years, in the constellation Leo. AD Leonis is a main sequence star with a spectral classification of M3.

And then there is this from intellihub, which, I still don't feel the best about that site. They are very sensationalist, but this could be something, it could be nothing.

Intense solar storms and space weather over the last week has revealed to researchers that some type of celestial object with a rather large mass may be approaching Planet Earth from the southerly rear side and is affecting how our planet is charging.

“We have had over ten hours of intense solar storms today–four of those hours being a K5 on the Kp Index–so folks we are going to see a lot of earthquake and volcanic activity along with an uptick,” the narrator of the YouTube channel World News Report Today explained in a video posted to the platform last Saturday. “…the surface charging on planet Earth is extensive folks–probably the biggest charge I have ever seen in a single day event.”

The channel’s narrator points out in the video that Earth has been receiving “intense charging” but says that the core currently remains unaffected.

To make matters worse, the Earth is receiving an intense bow shock.

“We have a pretty good bow shock happening on our bow but the rear of planet Earth traveling through space is actually seeing more pressure than the bow,” he explains. “Look at the rear and it penetrated into the atmosphere here–you can see that it’s quite intense as far as pressure on the backside or the nighttime side of Planet Earth.”​

Coincidentally, another YouTuber and Planet X researcher Angry Catfish Briggs told Intellihub during a sitdown interview in mid-September that the rear of the planet is experiencing major pushback or “backpressure” which can only be explained by an approaching large mass.

The C's did say the comet cluster would present as a solid body at first.

Space Weather reports that a rare recurrent naked eye nova outburst has been spotted in Ophiuchus. It's thought to repeat every 20 years but the last time this happened was in 2006 so it's been just 15 years. Whilst it's apparently visible to the naked eye, they say that binoculars or a telescope would be best. Full article below.

Rare recurrent nova outburst visible in constellation Ophiuchus

Recurrent nova RS Oph is in Outburst. The last large outburst of RS Oph occurred in Feb. 2006, when it reached visual mag 4.5.

Every 20 years or so, a thermonuclear explosion occurs on the surface of
RS Oph, a white dwarf in the constellation Ophiuchus. This week it happened again. On Aug. 8th, the brightness of the tiny star increased 600-fold, from magnitude +12 to +5. Keith Geary of Ireland was the first to notice. Hours later, Italian astronomer Ernesto Guido and colleagues photographed the outburst using a remote-controlled telescope in Australia:

This is called a "recurrent nova," and it is rare. In the whole Milky Way galaxy, only 7 star systems are known to produce such explosions.

RS Oph is actually a binary star--a very lopsided one. On one side is a white dwarf, on the other is a red giant.
There's very little distance between the two, so the gravity of the white dwarf is able to pull gaseous material off the larger star down onto itself. Every couple of decades, enough matter accumulates to trigger an explosion. The last time this happened was back in 2006.

At 5th magnitude, the current outburst is visible to the unaided eye, albeit just barely. Binoculars or a telescope will allow you to see it with ease. Look south after sunset. Ophiuchus hangs high in the sky just above the better known constellations Scorpius and Sagittarius.

Sky maps: simple, detailed, really detailed.


Variable star observer Filipp Romanov of Yuzhno-Morskoy, Russia, has just seen RS Oph and estimates that its magnitude has increased further to +4.6.

Recurrent nova RS Oph in outburst Taken. Details: I observed RS Oph with the naked eye and estimated: +4.6 mag. I took photos from my small homeland on August 9, 2021, from 15:19 to 15:22 UT. I have been waiting for several hours, and sky cleared for few minutes.

Another recent article that may be of interest is the discovery of what is thought be the largest and furthest filament of gas in the Milky Way; they even speculate it may be part of a new arm. In the article they briefly explain that mapping the galaxy is difficult and that could be the reason why it's only just been discovered.

Some other interesting points from the article include:
- "The question about how such a huge filament is produced at the extreme galactic location remains open," [...]
- "it is puzzling that the structure does not fully follow the warp of the galactic disk."[...]
- it appears to lack a certain "wobbly" feature that other spiral arms of our galaxy exhibit (the traces of an ancient intergalactic collision).

Alert Notice 752: Rare Outburst of Recurrent Nova RS Ophiuchi
August 9, 2021
Coordinates (J2000 from VSX): 17 50 13.17 -06 42 28.6 (267.55487 -6.70794)
The recurrent nova RS Oph is in outburst at a visual magnitude of 4.8, according to observations
by AAVSO observers Alexandre Amorim (AAX) of Florianopolis, Brazil, Eddy Muyllaert (MUY) of
Oostende, Belgium, and Keith Geary (GKI) of Shercock, Co. Cavan, Ireland.

Data in the AAVSO International Database show that the last outburst of RS Oph
occurred in February 2006, when the star reached visual magnitude 4.8 and was brighter than
10.5 for about 80 days;
RS Oph returned to its normal inter-outburst behavior approximately
120 days after outburst maximum. Previous outbursts have been recorded in 1898, 1933, 1958,
1967, and 1985 with a probable outburst in 1945.

While the length of the interoutburst interval in RS Oph varies greatly, the shape of the
outburst and recovery to interoutburst is remarkably similar from outburst to outburst.
a very interesting analysis of the behavior of RS Oph, see B.D. Oppenheimer and J.A. Mattei,
JAAVSO, 22, 2, 105 (1993), or Oppenheimer and Mattei in Compact Stars in Binaries, proceedings
of IAU Symposium 165, ed. J. van Paradijs, Edward Peter Jacobus van den Heuvel, and Erik
Kuulkers, Kluwer Acad. Publ., Dordrecht, 457 (1994).

Observing recommendations: Please observe RS Oph as it continues to evolve, with observations
of all types (visual, CCD, DSLR, PEP, spectroscopy) and multiple bands as instrumentation
