After a period of inaction the orbital period of Cosmos 2519 dropped slightly from 97.909 minutes to 97.772 minutes during December 14-16.

Has there been any official conformation from the Russians that Cosmos 2523 is actually object E from this launch? - the object catalogued on October 31 in a 554-664 km orbit?

NK-forum:
23 июня – Космос-2519 (14Ф150 "Напряжение" ), Космос-2521 (спутник инспектор), Космос-2523 (ПО) – Союз-2-1В/Волга – Плесецк 43/4 – 21:04:33

 (ПО) apparently analogous "TBD"

Russian friends can help ?

So it would appear that the people using the NK Forum haven't seen official confirmation either ...........

Hate giving web links;
[2017-037E] Cosmos 2523
under UNOOSA Secretariat's remarks:
"The registration submission for this space object is presently being processed by the United Nations Secretariat. Date of launch is date of deployment from Cosmos 2521."

According to my informations, Cosmos 2519 is 14Ф150 №8120.

https://www.kosmonavtika.com/lancements/2017/23062017/23062017.html
No. 8120 does not seem to be 14F150 no. 2.
Rather no. 1.

Another explanation of the early references to №2, is that №1 was intended to fly on a different rocket?

There does appear to be a 14Ф150 №2:-

Cosmos 2519 has engine K50-10.5 from OKB Fakel.

http://www.fakel-russia.com/images/content/o_kompanii/letnaya_istoriya/KA_s_oborudovaniem.pdf

The K50-10.5 thruster is also mentioned in an article in the 3/2015 issue of the NPO Lavochkin magazine "Vestnik" about cooperation between NPO Lavochkin and OKB Fakel.

https://www.laspace.ru/upload/iblock/a81/a81ab7a06d732871d12138a11250f4cd.pdf
(see p. 35-36)

It is said to be 1.5 times lighter than the K50-10.1 thruster used on many Russian satellites. There is a unit consisting of a single K50-10.5 thruster called DB-1 and a unit consisting of three K50-10.5 thrusters called DB-3. Flight models of DB-1 and DB-3 were said to have been delivered at the time for "the first satellites of a new series, namely MKA-FKI (PN3) and EOKA". The same thruster will also be used by Lavochkin's Rezonans satellites.

MKA-FKI/PN-3 (also known as Konus-M) was a proposed astronomical satellite for gamma-ray and X-ray studies that has now apparently been canceled. Rezonans is a satellite for magnetospheric studies, four of which will be launched together in 2019. Testing of the K50-10.5 thrusters for Rezonans is described in detail in this article in the
3/2017 issue of Vestnik magazine.

https://www.laspace.ru/upload/iblock/676/676bc74dae2fe0e9da6e03b6d0a630a1.pdf
(see p. 27-35, with a drawing of the engine unit on p. 29)

EOKA might well be Kosmos-2519. I can't immediately find any other reference to it on the web. "E" usually stands for "experimental" and "KA" for "kosmicheskiy apparat" ("satellite"). Could the "O" stand for "optical"?

Both MKA-FKI/PN-3 and Rezonans are designed on the basis of the Karat-200 bus, so there's a good chance that EOKA uses the Karat-200 platform as well.

More technical information on the K50-10.5 thruster can be found in this English-language brochure of OKB Fakel.

That's usually translated as "optiko-elektronnyy" (оптико-электронный), so in that case you would expect OEKA rather than EOKA.

One of the leading designers of Kosmos-2519 may be Nikolai N. Klimenko, a deputy of NPO Lavochkin’s general designer Aleksandr Shirshakov. He joined Lavochkin in 2012 after a 40-year career in the military, where he worked his way up to the rank of lieutenant general in the Space Forces.

Klimenko participated in round-table discussions on the use of small satellites for military purposes during the “Army 2015” and “Army 2016” military expositions near Moscow, where he talked about plans to build military satellites on the basis of the Karat-200 platform.  This was briefly mentioned at the time in articles covering these events in the weekly “Voenno-promyshlennyy kuryer” (“Military Industrial Courier”) (in Russian).

https://vpk-news.ru/sites/default/files/pdf/VPK_28_594.pdf
see p. 8
https://vpk-news.ru/sites/default/files/pdf/VPK_39_654_2.pdf
see p. 8

Klimenko also published an article summarizing his presentation at the Army-2016 forum in the December 2016 edition of the journal “Vozdushno-kosmicheskaya sfera”. He talked not only about satellites, but also about solar-powered unmanned aerial vehicles which could hover above the Earth’s surface for up to  100 days at altitudes of up to 25 km and in his words could be used for high-altitude reconnaissance missions over war zones such as Afghanistan and Syria.

http://www.vesvks.ru/vks/article/malye-kosmicheskie-apparaty-ozhidaniya-i-realnost-16189

One of the articles seems to suggest (although the wording is somewhat open to interpretation) that Lavochkin produced an experimental military satellite using the Karat-200 bus, but that no orders had yet been received for its serial production at the time of writing (in late 2016). This might be a reference to Kosmos-2519, even though it had not yet been launched at the time. The only other military satellite known to be under development at NPO Lavochkin is the Araks-R radar reconnaissance satellite, which uses the heavier Navigator platform. 

There is a picture in Klimenko’s article that shows him giving a presentation during the Army-2016 event with a slide in the background (see below). That seems to show a Karat-200 platform with a telescope as the payload. What could this be?

Lavochkin is working on a Karat-200 based solar observatory called  Arka, but that payload looks totally different (see below). Moreover, one word I can make out on the slide is “monitoring”, which is not suggestive of an astronomical mission. It could refer to monitoring of the space environment. Karat-200 (along with the Navigator bus) is known to have been considered for satellites intended to observe the geostationary belt. Klimenko wrote about those plans in an article for the NPO Lavochkin “Vestnik” magazine in 2015 (see replies 134/135/136 in this thread).

“Monitoring” could also refer to remote sensing of the Earth. Klimenko is quoted as saying in one of the articles that Lavochkin has been working on civilian optical and radar remote sensing satellites using the Karat-200 bus, so the image could show one of those (but the borderline between civilian and military remote sensing is vague and let’s not forget that he was talking at a military event).  He also talked about satellites with membrane optics that could have a resolution of 2-2.5 m from geostationary orbit (like the one Ball Aerospace is now developing for DARPA under the MOIRE program), but the payload seen in the picture looks like a conventional telescope rather than a membrane optical imager. 

So could this picture show a satellite similar to Kosmos-2519? The least one can say is that the Kosmos-2519 “mother satellite” is likely to carry a payload of its own. The Karat-200 platform alone weighs about 250 kg  and the payload capacity of the Soyuz-2.1v/Volga to a Sun-synchronous orbit is 1.4 tons, so there would be plenty of margin for a significant payload on the mother satellite itself apart from the two subsatellites. A Ministry of Defense statement after the launch said the satellite would be used for both Earth remote sensing and photography of objects in space. That could mean that the mother satellite is performing the remote sensing mission (which would be consistent with its near Sun-synchronous orbit) and the two subsatellites are performing the satellite observation missions.       

The least that these articles tell us is that the Karat-200 platform has indeed been considered for military missions.

Is there any current orbital data from 2017-37E?
I would like to ask this question again.

Still in 555 x 663 km orbit - no evidence of manuevers since shortly after it appeared.
Here are the 2017-37 objects with E in red

Following on from Apachhi's post, here are the pre- and post- manoeuvre orbital data:

2018 Feb 13.888    97.88 deg      97.905 minutes    651 km      666 km   208 deg (AoP)
2018 Feb 14.452    97.92            97.544                 619           664         231

I wonder whether the perigee of Cosmos 2521 will drop further for a rendezvous with Cosmos 2523 which is in a 555-663 km orbit?

At present the orbital planes of the two satellites are about 2 degrees apart, so something would need to be done about that for a rendezvous - unless a "fly-by" without lingering was planned.
