Interesting, I'm right in the 10-30 seconds, thanks for posting.

That visibility chart is for the boost phase. About 9 minutes into the flight is the gas release. Sometimes those are pretty spectacular. There is more detail in that article.

The "seconds" window....is that when in the flight it could be visable? i.e. - 60 to 90 seconds means I could view it from 7:59:00 to 7:59:30 assuming a launch at 7:58:00?

Funny how those perfect circles stop at the Canadian border and coastline as if saying: Huh? How would we know anything about those places?

I thought the Black Brant was a Canadian designed rocket?

Its because of the wall....up to space....er...or something like that. Its all so confusing. I think I read about it in a book about throne games.

30-60 second ring here. I'll have to keep checking the site for schedule updates. The weather forecast is for cloudy much of Saturday, partially clearing in the late afternoon, so maybe there'll be a chance by evening.

It is, and the Upper stage of the BBXII is a BBV, which is Canadian built. The boosters, Talos and Terrier, are American built if I'm not mistaken. In any case, NASA uses rather a lot of the BB series, imported from our friends to the north.

The very top is actually 2 rockets, a BBV that is topped with a Nihka.

Per Wiki:
Black Brant XII (a.k.a. Talos Terrier Black Brant Nihka), a four-stage rocket with a Mk 11 Mod 5 Talos booster first stage, Terrier booster second stage (pre 2013 Taurus booster motors were used), Black Brant V third stage and Nihka fourth stage

I think that's just the time it takes for the rocket to rise from below the horizon at a given viewer location. Think about the most inner ring. Why would they lose sight after 10s?

"A four-stage Black Brant XII rocket will be used..."

That website says four-stage, is that a mistake? It looks like a 3 stage to me, or is there something extra like a boosted dart that counts for the fourth stage?
The fourth stage - called Nihka - is fin-less, because it's ignition altitude is above any significant atmosphere. Therefore it is not visually apparent in photos. If I remember correctly, it's spin stabilized.

Should've named it Kiwi instead of Nihka. 😁

The Nihka stage is more or less the black section in between the silvery nose cone and the silvery band below. (Or is that a faring around the Nihka?)

I can't find it now; I've read somewhere that the name is a word from one of Canada's indigenous peoples. It means... damn, I can't find it now. (No, "damn, I can't find it now" is not what it means.)

It is Canadian designed. But NASA and other agencies have been using the vehicle as well with their own payloads for decades. Wallops Island has launched many Black Brants over the years. And various American designed boosters have also been used with the BB.

In case anyone is planning a "road trip" to view the launch, it is now scheduled for no earlier than 8:02 PM, with a 40 - Minute "window'", Saturday, May 8, 2021.

The Wallops Island Visitor Center WILL NOT BE OPEN . . .

HOWEVER, there are other recommended viewing sites.

Viewing Wallops Island, VA Rocket Launches

Chincoteague Island has long been known for its Wild Ponies and picturesque beach. Thanks to NASA, Chincoteague is becoming known for something new and exciting... the go to destination for viewing rocket launches from Wallops Island.

At least 8 missions will leave from the Mid Atlantic Regional Spaceport located at NASA's Wallops Flight Facility on Wallops Island, Virginia. It's all part of a $1.9 billion contract between Dulles, VA based Orbital Sciences Corporation and NASA to deliver precious cargo to the International Space Station.

The islands of Chincoteague and Assateague on the Eastern Shore of Virginia are perfectly positioned to offer spectacular public viewing sites as well as waterfront lodging options on the Chincoteague Bay offering private balcony views.

Please be aware that a variety of unforeseen circumstances may cause the rocket launch to “slip” for a day or longer. There are weather, mechanical, or logistical situations that may occur to interrupt the launch schedule. Chincoteague and Assateague Islands offer endless opportunities to stay and play while awaiting the next “window of opportunity.” Explore our website for options.

We have compiled a list of what we have found to be the BEST ROCKET VIEWING SITES on Wallops, Chincoteague and Assateague Islands. Enjoy your time in the land of rockets and wild ponies!!

Please Note: Some viewing locations may be off limits for some launches as determined by NASA for safety reasons. The most up to date information on all launches can be found on the NASA Wallops Flight Facility website.

I've got rain rolling in starting about launch time Saturday and going non-stop until Sunday night. :( Don't think I'll be able to see anything

You may be able to see it via the internet. I tuned into the Wallops Island website this morning - https://video.ibm.com/channel/nasa-tv-wallops and scrolled down to watch an older Black Brant ASPIRE rocket launch from 2018 (https://video.ibm.com/recorded/116993176) They launched 2 small test rockets immediately before the BB.
