December 25
And:
China launches in 2018 (times in UTC)
<snip>
02 - January 11 (23:18:04.616) - CZ-3B/YZ-1 (Y45/Y5) - XSLC (07-82), LC2 - Beidou-3MEO7 'Beidou-26'; Beidou-3MEO8 'Beidou-27'

China launch schedule

2018
<snip>
January 26 29 - CZ-2C - XSLC, LC3 - YG-30-04 Yaogan Weixing-30-04A, B, C (CX-5 Changxin-5 (4A, 4B, 4C))
February 15 (?) - CZ-3B/YZ-1 - XSLC, LC2 - Beidou-3M5; Beidou-3M6

January 12

And given that successive orbital launches from Xichang can happen as quickly as a 2-3 week interval;

It tracks that, given no other information, such as a satellite or launch vehicle processing delay, this launch can happen on (or near) February 15.

This is one day before Chinese Lunar New Year, which often brings a hiatus to launch activities, due to extensive leave-taking and travel.

China Aerospace Philately issued a notice saying that the launch will take place at 20:00 local on February 11.

Looks like the launch time is incorrect:

Considering that Chinese New Year is only 4 days away, that should count as good luck for the next year.  ;D

Ah, so the reason the Long March 3B/YZ-1 launch was pushed back to today was a visit by Xi Jinping to Xichang Satellite Launch Centre on the 10th.

China sent twin BeiDou-3 navigation satellites into orbit
http://www.xinhuanet.com/english/2018-02/12/c_136970281.htm

XICHANG, Sichuan, Feb. 12 (Xinhua) -- China sent two satellites into orbit on a single carrier rocket for its domestic BeiDou Navigation Satellite System (BDS) Monday.

The twin satellites, which form a network with four previously launched BeiDou-3 satellites, were the fifth and sixth satellites in the BeiDou-3 family. They entered orbit more than three hours after the launch from the Xichang Satellite Launch Center in southwest China's Sichuan Province.

Hmm...Why not visit, AND view a launch?  It was a mid-day LT, and he IS head of government and head of state.

Did he (or his political advisers) not want to be on-site in case of the slight chance that the launch would less than nominal?

Or security concerns about launch hazards?
