What is the original brightness of a star when it suddenly flares up to many times?

A star the size of our Sun or smaller is too small to become a "Nova", so we can expect that the original brightness of a "nova" star is probably brighter than the Sun; possibly a lot brighter.

The original brightness of a star before it flares up can vary significantly depending on the star's size and type. When a star suddenly flares up to many times its original brightness, it is typically due to an increase in energy output caused by internal processes like nuclear fusion reactions or interactions with other celestial bodies. This sudden increase in brightness can be temporary or long-lasting, depending on the specific circumstances of the flare-up.

Is climate affected by solar flares?
Solar flares do not directly affect Earth's climate because they release energy in the form of x-rays and extreme ultraviolet radiation, which are mostly absorbed by the Earth's atmosphere. However, solar activity, including solar flares, can indirectly influence climate by affecting the sun's output of energy and its interaction with Earth's magnetic field.
What are blasts of gas from the sun's atmosphere that sometimes forms enormous loops?
Solar flares are blasts of gas from the sun's atmosphere that can form enormous loops due to the sun's magnetic field. These loops are known as coronal loops and can span many times the diameter of the Earth. Solar flares can release massive amounts of energy and particles into space.
What is the difference between a twelfth magnitude and fifteenth magnitude star?
The main difference is brightness: a twelfth magnitude star is brighter than a fifteenth magnitude star. Magnitude is a logarithmic scale, so each step in magnitude represents a difference in brightness of about 2.5 times. This means a twelfth magnitude star is approximately 12.5 times brighter than a fifteenth magnitude star.
Why must astronmers figure out a star's distance to calculate it's actual brightness?
A star's actual brightness, known as its luminosity, is related to its distance through the inverse square law. This means that a star's apparent brightness decreases with increasing distance. By determining a star's distance, astronomers can accurately calculate its luminosity, providing crucial information about its size, temperature, and energy output.
Are stars different sizes and brightness?
Yes! Some stars are supergiants, which means that they are high-mass stars. They explode in a supernova towards the end of their life. These stars are generally brighter than others. A star's brightness also depends on its temperature. Red stars are the coolest temperature, followed by orange, yellow, white and blue stars.
What is fashion nova?
A trend which suddenly flares up to many times its original brightness and then gradually fades over a period of weeks to years.

What does the sun erupting mean?
There are huge (several times the size of the earth) storms on the surface of the Sun, sometimes these cause gigantic flares to expand out from the surface of the star into space. These "flares" are said to "erupt".

What is the stars actaul brightness?
That is called "absolute brightness" or "absolute magnitude". It is defined as how bright a star would look at a standard distance (10 parsec, to be precise). The brightness of stars can vary a lot; some stars (supergiants) are millions of times as bright as our Sun, others (red dwarves) are thousands of times less bright. (Our Sun is in the top 10 percentile, though.)
