The launch year in the title needs to be updated to 2019 and the name changed to Aditya L1.
Thanks! Done!

Aditya-L1 may get a sibling at L5   :)

According to ADCOS Chairman, and former ISRO chief and cosmic ray scientist U.R. Rao, a second spacecraft can be sent to Point L5, about 1.3 million km away and at a 30-degree angle to L1, for a fuller picture of the sun. It could follow L1 a few months or a year apart, he told The Hindu.

Quote
Dr. Rao said early discussions have taken place on a possible L5 mission. ISRO, he said, could use the qualification model of the spacecraft which goes through the same tests and is as good as the final flight model.

“Activities related to the Aditya-L1 mission have started,” confirmed ISRO Chairman A.S. Kiran Kumar. “Two [spacecraft to sun] together will become unique. Having another one at L5 will give a significant advantage in measurements. We have to still take it up and it must go through all the regular approval processes through the Union Cabinet and budgeting.”

Yes, its recently been filed in ESA's Helieophysics Satellite database as Aditya-L5 Solar Observation Mission, PSLV (XL) 20xx
in the data base there are four Satellites (two to L1 and two to L5) with two being the primary satellites and the remaining two being the replenishment satellites.

Quote
Visible Emission Line Coronagraph (VELC), the main payload for the mission is being built at the Indian Institute of Astrophysics, Bengaluru. The advisory committee for space sciences is keeping tab of the projects.

Quote
Jagdev Singh, Principal Investigator, VELC mission, Indian Institute of Astrophysics, Bengaluru said, the VELC is undergoing various stages of testing.

“We have finished the designing part. The engineering and flight models will be ready in two years. The Sun’s corona experiment can be launched in three year’s time.”

Quote
“Though the project was being discussed from 2006 the works started only in 2010. We are confident of launching it in 2019,” he said. “The experiment will be placed in the Lagrangian point (L1). It is about 1.5 million kilometres from Earth where the gravitational force due to the Earth and the Sun works in the opposite direction and the payload put at that point can see the Sun all the time without any eclipse,” he added.

Speaking to reporters here on Saturday, Mr. Annadurai, after inaugurating the INSPIRE - DST Science Camp at VOC College, said Aditya, the first Indian mission to study the sun, would be launched in 2019 - 2020. Preliminary works for this mission are progressing as planned.

India is all set for the take-off of its maiden mission to the Sun by the year 2019. Indian Space Research Organisation (ISRO) chairman AS Kiran Kumar on Monday, during an interview at the FICCI at 90 event said, “Aditya-L1, India’s maiden mission to the Sun, will be launched in 2019”.

Following is a very comprehensive report from the Hindu Newspaper on Aditya scheduled to be launched in 2019

Here comes the sun watcher, India's Aditya-L1

Quote
Sometime in 2019 or 2020 India will send ISRO's solar mission Aditya-L1 to a vantage point in space, known as the L1 Lagrange point, to do imaging and study of the sun. This launch will happen in the early part of the next solar cycle - an occurrence in which sunspots form on the face of the sun, growing in size and number and eventually diminishing, all over a period of eleven years. It will be a mission of many firsts.

Quote
The so-called L1 point is 1.5 million kilometres away. Here, due to the delicate balance of gravitational forces, the satellite will require very little energy to maintain its orbit. Also it will not be eclipsed from the sun. The 1,500-kg class satellite will be programmed to orbit this point and image the sun's magnetic field from space for the very first time in the world. Scientists hope to capture the close-ups of the sun from here, uninterrupted by eclipses for years.

Quote
Few other space agencies have successfully placed their satellites at this location. Among the few, the Solar and Heliospheric Observatory (SOHO), a NASA-ESA collaboration involving America and Europe, and NASA's Advanced Composition Explorer (ACE) are at L1 exclusively to study the sun and space weather, respectively. Aditya-L1 is expected to be the very first to study from space two months from the time of launch, the magnetic field of the sun's corona. The corona is the outer layer that we see during total solar eclipses. It will be the first 100% Indian mission which will not only negotiate a challenging orbit, but will also benefit the global scientific community in understanding the sun.

Quote
Earlier, the NASA-ESA mission SOHO was launched in 1995, and while it made many discoveries, its coronagraph, meant to image the sun, broke down shortly after the mission commenced. Hence there is currently no satellite imaging the sun from space. Aditya-L1 will not only fill this gap it will also literally, look deeper into the sun than SOHO. "The nominal mission lifetime is expected to be five years, though it is expected to go on for much longer, perhaps even ten," says Dipankar Banerjee from Indian Institute of Astrophysics (IIAP), Bengaluru, which is collaborating with ISRO on this project.

Quote
The mission will carry seven payloads, consisting of a coronagraph, equipment that will image the sun using ultraviolet filters, X-ray spectrometers, and particle samplers all being made within the country. The largest payload, or instrument, aboard the satellite, will be the Visible Emission Line Coronagraph (VLEC). This can view the sun more closely than has been done before even by SOHO.
