The Safir serial numbers to date are, I believe:


Omid  OES.0001
Omid  OES.0002
Rasad UIS.0001
Navid ERS.2002
[failures 2012-2014, unknown]
Fajr    LSB.2001

Do others concur? Any interpretation?   I speculate the letters may represent an internal payload codename.
To be super speculative, perhaps the first digit is a Safir version number and the other digits are a serial for launch attempt within
the payload project series - if so it would imply a Navid precursor failure and that the post Navid failures
were not Fajr.  But obviously they could easily represent something else.

From TLEs I would say the launch occured at 08:52 UTC, add or take a couple of minutes.

I estimate 0850 UTC +/- few minutes.

Just to reminde all - the satellite is equiped with cold gas propulsion system.

Ah! So THAT'S what the problem was! All weekend some right-wing news sites of my acquaintance have been shrieking about Iran having an 'ICBM capable of delivering a nuclear warhead against America'. I wondered what had triggered that and now I know!

I'd remind them that:

1) There are no warheads;

2) The RV capable of protecting the warhead during entry and descent is quite a technical feat in its own right.

That said, she's a very graceful-looking LV and I have to add that, frankly, a capable photo-recon satellite is even more useful (and dangerous to one's enemies) than a ICBM that, by definition is a one-shot suicide weapon.

Actually I wouldn't even call that satellite a "photo-recon" satellite, since they seems to be nothing more sophisticated than many of the microsats built by various universities nowadays around the world. This one apparently has cold gas thrusters, which again isn't exactly beyond university students level technology.  ;)

Speaking of the rocket, was it conclusively proved that the Safir's 2nd stage is powered by engines borrowed from the Russian R-27 SLBM's verniers? (I knew that this was talked about before for Iran and also North Korean rockets, but I am not sure if there are other possible origins)

Well, NORAD has found it rather quickly.  :P

40387/2015-006A: 224 x 470 km x 55.53 deg.
40388/2015-006B: 224 x 460 km x 55.54 deg.

Where do we get those? I used to check n2yo.com, but it does not show anything yet.

OT, but most likely www.space-track.org. That is the US government site that public orbital data is first posted too. N2yo.com, along with other similar sites source data for public (Non US intelligence) satellites from it.

So, Comet said that there was great activity at the Komeini launch site. Fajr used the old launch site. Should we expect a new launch «soon«?

Janes defense says no.

The article published on their website claims that construction of the new launch pad is still not complete and it takes at least a few months for it to be ready .

The claims aren't about Safir.  They are based on the bigger rocket assumed to be preparing to fly from the bigger launch pad.  I believe they originated with a recent news report from Israel.  But of course this was all "old news" to readers of this site.

I'm more interested in Iran's solid motor work, which has already produced militarily useful shorter range missiles.

Omid  OES.0001
Omid  OES.0002
Rasad UIS.0001
Navid ERS.2002
[failures 2012-2014, unknown]
Fajr    LSB.2001

The successful Omid launch featured vehicle GBS.0092 as seen below.

I think the third letter S means Safir. You may find a digit 3 in this position for Shabab-3 missiles.

Huh, I wonder where I got OES.0002 from. GBS.0092 seems an odd-one-out.

I believe the new name for this vehicle is Safir-e, as reported in

http://english.farsnews.com/newstext.aspx?nn=13931113001060

The first Safir was a suborbital launch and had serial HUS.0001.
