It was first observed on February 23, 1987.
SN 1987A [See Link] was a supernova in the Tarantula Nebula in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 168,000 light years from Earth, close enough that it was visible to the naked eye. It was the closest observed supernova since SN 1604, which occurred in the Milky Way. The light from the supernova reached Earth on February 23, 1987. As the first supernova discovered in 1987, it was labeled "1987A".
There are no exploding stars (supernovae) in our solar system. Supernovae occur in distant parts of the galaxy, outside our solar system. The nearest known supernova to Earth was Supernova 1987A, which was located in the Large Magellanic Cloud, a satellite galaxy to our Milky Way.
Supernova 1987A was useful because it was the first opportunity for scientists to study a nearby supernova in great detail. It provided valuable insights into the late stages of stellar evolution and the physics of supernova explosions. The data collected from Supernova 1987A has been instrumental in advancing our understanding of the life cycle of massive stars and the formation of elements in the universe.
The name is formed from SN (yes SuperNova), the year of discovery, then followed by a one or two letter designation. SN is optional.The first 26 of the year get designated with an upper case letter from A to Z. then, pairs of lowercase letters are used, starting with aa, ab.... etcetera Historical supernovae were known simply by the year they occurred: SN185, SN1572 SN1604. Since 1885, the letter notation was used.
It was first observed on February 23, 1987.
SN1987A was the the closest observed supernova since the invention of the telescope. The previous supernova, SN1604 was only observed with basic equipment and of course the naked eye.It also gave astronomers the ability to calculate it's distance at 168,000 light years.
The only date close to this that is Nova related was February 23rd when Supernova 1987A was observed.

Discovering supernova 1987A!

The absolute magnitude of the 1987A supernova shock halo is estimated to range between -9 to -10 magnitudes in the visible light spectrum. This value indicates the intrinsic brightness of the halo if it were observed from a standard distance of 10 parsecs (32.6 light-years).
SN 2006gy [See Link] was an extremely energetic supernova that was discovered on September 18, 2006. Although about one hundred times as luminous as SN 1987A, which was bright enough to be seen by the naked eye, SN 2006gy was more than 1,400 times as far away as SN 1987A, and too far away to be seen without a telescope.SN1987A [See Link]was a supernova in the outskirts of the Tarantula Nebula. It could be seen with the naked eye from the Southern Hemisphere.It was the closest observed supernova since SN 1604 The light from the supernova reached Earth on February 23, 1987.SN1604 [See Link] was seen on October 9th, 1604 generally a supernova occurs once every fifty years but the universe has been in a drought for these supernatural awesome events
SN 2006gy was the brightest and largest supernova ever discovered, scientists announced. The star was in the NGC 1260 galaxy, in the same direction as the constellation Perseus and may be a type of supernova previously predicted by theory but not observed. The conclusion was reached after extended observations of the supernova by both optical telescopes and X-ray telescopy. Currently, there are two possible explanations for the supernova's brightness, but both require the star in question to have been at least a hundred times as massive as the sun. Although the supernova is brighter than SN 1987A, which was bright enough to be seen by the naked eye, SN 2006gy is too far away to be seen by the naked eye.
