New Star to be Visible in 2022? Observations NOW requested.....
New Star Awaiting 2022? I am sure that many of you have heard the news about the prediction that there will be an enormously bright "new star" in the summer of 2022, poised between the constellations of Cygnus and Lyra, the result of a very close binary star which supposedly - in theory - collided in the 3rd century A.D., some 1800 years ago....
We should not wait until 2022 to start to monitor this star however....the distance modulus OR the event timing may be off by as much as a decade and observers might get to be the first to spot this once in a lifetime celestial event should it occur. BELOW is a current finder chart from Arkansas Sky Observatories showing the exact field of this star, with the 12th star marked in the middle with comparison stars annotated in this 22 x 15 arc minute field. I urge you to make monitoring this star part of your nightly observing routine!
ABOUT CHART: To avoid confusion, note that the star magnitudes do NOT have a decimal point (so as to not confuse for stars); hence, if you see "1240" for example, that represents magnitude 12.40
The star named KIC9832227, is 1,800 light years away and according Dr. Dr Matt Walhout, Dean for research and scholarship at Calvin College, in Michigan, the two stars gravitationally pulled together in their close orbit some 1800 years ago, and the light from this impressive celestial event will be arriving for us to actually SEE in the year 2022, only a few years from today. NOTE: a more commonly used catalog, the UCAC-4 astrographic catalog currently used by many astronomers, has the designation for this star:
Coordinates (epoch 2000) for this star are: (in the constellation of CYGNUS)
|Right Ascension||19h 29m 15.948s|
|Declination||+46° 37′ 19.89″|
|Apparent magnitude (V)||12.27 - 12.46|
UPDATE: January 11. A photometric series (using the balanced filters BVR and I) was made on this star at present on the evening of January 08 U.T. by friend and colleague Denis Buczynski of the British Astronomical Association (BAA). His magnitude measurements (CCD) were:
B = 12.7
V = 12.6
R = 12.4
I = 12.8
The star was already classified as a minor variable star (about 0.2 mag. variation) but changes should become far more dramatic in the coming months.
Since the constellations of Cygnus and Lyra are very high in summer skies for northern observers, this event - if it does take place - should be easily visible as a star suddenly "appears" in the sky over 10,000 times brighter than it presently is today. Even with large telescopes, this star is difficult for us to see. Even those with large telescopes and CCD photography are now seeing the star exactly as it was 1800 years ago, since it takes the light that long to travel through space to our vantage point. At the distance of this star, should the two stars actually have collided, the result would be a star brighter than nearly all in the sky.
But the jury is out as to whether Dr. Walhout's calculations and theory are correct.....only a few years until we find out. And - just in case the distance or the calculations are off slightly, which is very likely - the event okf this sudden star flashing brightly in the sky might take place at any time. Even tonight. So - HEAD'S UP! Let us hope this prediction holds true.
