Astronomers Find New Comet, How Do You See It From Indonesia



KOMPAS.com – Astronomers have just discovered a new comet. According to the Minor Planet Center on Sunday (11/11/2018) this comet was first reported by Don Machholz.

Machholz observed the comet visually first time Wednesday (11/07/2018) then or around Thursday (08/11/2018) with Indonesian time.

Two Japanese observers, Shigehisa Fujikawa and Masayuki Iwamoto, saw separately the same at the same time.

This discovery was followed by other astronomers. One of them was the Indonesian amateur stranger Marufin Sudibyo.

"At that time, the size was +10, now it's +8," said Marufin to Kompas.com on Monday (11/11/2018).

"It seems to be bright," added Marufin.

When asked if the comet would pass close to the ground, Marufin explained that the space object was quite far away.

"But the perihelion (nearest road to the sun) reaches Mekurius course," Marufin said via SMS.

"It will be clear enough if (comet) is not broken down," he said firmly.

He also explained that the declination of this coma (equatorial coordinates) is negative.

"That means it is easily seen from the southern hemisphere," said Marufin.

"The decline is at most -19, which means that even from the equator line it can be seen up to 71 degrees. It's quite loud," he added.

Even from Indonesia, Marufin explained that this comet was a telescopic type. In other words, this comet can not be observed with the naked eye.

But for those of you who want to capture the new comet, Marufin gives some tips.

"Portrait with a DSLR camera with a 50mm or larger lens," he said.

Marufin also had time to simulate the best time for this comet observation. Unfortunately, the simulation result is disappointing.

"This comet can only be seen once between November 12 and 22," said Marufin.

"After that, it does not seem anywhere from Indonesia," he said.

He explained that the best observation for this comet is 04.00 WIB.

"(Its position) is on the north side of Venus," said Marufin.

"But from day to day the position has decreased or the height is getting lower," he explained.

To distinguish from other celestial bodies, you can observe diffuse comet lights or not a bright spot.

To clarify, Marufin gave a comet shot called C / 2018 V1.

In the picture it appears that this comet is adjacent to the gamma star Virgo (Porrima) at + 3 magnitude. Marufin explained that this photo was taken on Monday (11/12/2018) in Japan.

"Astrophotographers only use Canon EOS 60Da DSLR cameras and 200 mm telelines. ISO 12800, 10 seconds exposure," he said.

"The astro photographer's name is Shozo Sasaoka, an amateur astronomer," he explained.

Other comets

Marufin also explained that in December there should be two bright comets. First, this comet is estimated to have a size of +7 in December.

The other is the Wirtanen comet that has a magnitude of +3.5. According to his theory, Wirtanen comets can be seen without tools.
