A lucky house

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

So, launch delayed by 24 hours.
The reason for the delay was Xi Jinping visited XSLC the day before yesterday

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.

From Xinhua

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.

Can anyone with better eyesight than mine (99% of the population!) see the launch vehicle serial number on any of the photos please?

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?
