I noticed this appearing as a channel variant on the BBC schedule page.

It's listed as starting on the 23rd of January.

With BBC SD services being closed down on satellite, a new national SD service will be provided for those who are not yet in a position to receive HD versions of the BBC channels.

BBC One Nightlight will have its own version of the "red screen" in place of regional news:

According to Sky's webpage about the BBC One Upgrade in England. Here is an example of what the Nightlight static caption will look like from January.



The list of Sky boxes in SD affected by the SD  switchoff are listed here in this webpage.

Where did you find 'Thusnus BBC one sd'?

The schedule for that is not yet online. If it is I cannot find it.

Please can you tell me where the 'SD' schedule is?

In the URL you mentioned I already found that but no schedule is showing. 
Thanks

Good to see that Sky appear to offer a free upgrade to Q - they seem to have been reluctant to shift people off of customer owned equipment (except when the Thomson HD boxes needed to be swapped since they weren't going to get a major update). I can't imagine there are that many subscribers with SD boxes anymore anyway.

I still have one as my multiroom box but these days only used for tests.

12420 h 27500 is showing two bbc nightlight services the other is showing BBC News Channel in SD.

The static caption had the above with red button/network music.

[Jimbo2022]

12422H SR 27500 FEC 2)3 DVBS QPSK

6411 and 6491 are the same channel - BBC One Nightlight
6417 is BBC News
6481 is BBC Radio Wales
6487 is BBC Radio Foyle

But this mux is hard to pick up on some receivers. There are multiple empty service labels too - IE not on air at present

On the tv channels there’s some black and white lines which aren’t on the regular SD channels.
