A star usually weak in brightness is to attract astronomers and observers to the sky due to an explosion that made it visible in the naked eye, especially in the southern hemisphere.
Known as “new”, the phenomenon caused the celestial body to suddenly increase its brightness and impressive, which seems, in fact, a new star in the night sky.
The term “new” refers to a moderate stellar explosion. Unlike a “supernova” that completely destroys the star, the new allows the object to survive the event and even repeat the process in the future. A supernova is much more powerful and marks the final collapse of the star, which can lead to a neutron star or a black hole.
The protagonist of the show is the V462 Lupi, located in the constellation of Lupus, the wolf. The event was first detected on June 12 by an international project called Asas-SN (English acronym for something like “Search Supernovae Automed”), led by Ohio State University, USA.

Prior to the explosion, the magnitude of the star V462 lupi was +22.3, which means that its brightness was too weak to observe without specialized equipment.
With the explosion, the star’s shine increased surprisingly. Remember that on the magnitude scale, the lower the number, the brighter the object. Stars with magnitude up to +6.5 can be seen with naked eyes in places with little light contamination.

As a new
According to the website Space.comThe classification of events as a new classic was confirmed by Yusuke Top, astronomer of the University of Cap University in South -Africa.
This type of explosion occurs in binary systems, when a white dwarf (a very dense and compact star) consumes material from a neighboring star. Over time, the accumulated matter is heated, even causing a nuclear fusion reaction to the surface of the white dwarf.
This reaction releases a large amount of energy, making the star temporarily much brighter. Therefore, the new can be observed even for those who do not use professional teams. Two days after the discovery, members of the American Association of Observers Star Variables (AAVSO) reported that V462 Lupi, with a magnitude +7.9, could already be seen with medium -sized binoculars.

How to observe the explosion of the star V462 lupi
According to the organization Sky & telescopeDuring the days, the new continued to increase the brightness, reaching the magnitude +5.5 Saturday (21) and became visible in a bare view in places with dark sky. However, Aavso’s latest data show that the star’s shine has already begun to decrease, indicating the gradual end of the program.
Before the V462 lupi disappears again, anyone who wants to observe -enjoy it in the coming days, especially during the phase of the new moon. Ideally, seek places away from the city’s lights and use a 10 × 50 binocular, which offers a good field of view.
To find the new one, simply find the region between the stars Delta Lupi and Kappa Centauri, in the constellation of the lupus. The use of observation applications, such as Star, Star Walk or Sky safari.
