The soon-to-be launched Maxar-built #SXM8 features our 1300-class platform, the leading spacecraft platform for communication #satellites. This high-power broadcasting satellite is more than twice as powerful as the 1st generation @SIRIUSXM constellation.

It's getting busy out there... the entire, active, East Coast SpaceX recovery fleet is offshore so it's time for a map!

Droneship support ship GO Quest will have to sail direct from the CRS-22 LZ to the SXM-8 LZ in the next few days.

GO Searcher and GO Navigator departed from Port Canaveral last night for the SXM-8 mission.

The Dragon recovery ships are back for another temporary fairing recovery assignment.

L-2 with no major changes. Still 60% GO on primary, 80% on backup day. Additional risks are low.

What is a Debris Cloud ?
It's the exhaust clouds that were formed during the CRS-22 launch. They're just hanging in the air as of now.
?
I think debris cloud rule is similar to detached anvil rule: the decaying remnants of a thunderstorm.
Here's a quote from a paper that I found on-line: Scale Dependence of Monsoonal Convective Systems over the Indian Ocean
https://journals.ametsoc.org/view/journals/clim/13/7/1520-0442_2000_013_1286_sdomcs_2.0.co_2.xml

...[T]he background convective cloudiness, might as well include some tops of midlevel cloud systems, isolated thick cirrus, or detached stratiform anvils of decaying convective clouds, and can be thought as the so-called convection debris that is often encountered during the winter monsoon over the Indian Ocean region...

Actually for this case it’s probably from 14 CFR Appendix G to Part 417 - Natural and Triggered Lightning Flight Commit Criteria. These are part of the Commercial Space Transportation regulations from the FAA.

Quote
Debris cloud means any cloud, except an anvil cloud, that has become detached from a parent cumulonimbus cloud or thunderstorm, or that results from the decay of a parent cumulonimbus cloud or thunderstorm.

The specific rule is from NASA’s Falcon 9 Launch Weather Criteria chart is
Quote
Do not launch within 3 nautical miles of a thunderstorm debris cloud, unless specific time- associated distance criteria can be met.

L-1 weather forecast.  Primary Day has improved to 70% 'Go'.  Backup Day remains at 80% 'Go'.  All additional risks remain Low.

SpaceX is targeting Sunday, June 6 for Falcon 9’s launch of the SXM-8 mission from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. The one-hour and 59-minute launch window opens at 12:26 a.m. EDT, 4:26 UTC, and a backup launch opportunity is available on Monday, June 7 with the same one-hour and 59-minute launch window.

Falcon 9’s first stage booster previously supported SpaceX’s Crew-1 and Crew-2 missions, which launched astronauts to the International Space Station. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be located in the Atlantic Ocean. A live webcast of this mission will begin about 15 minutes prior to liftoff.
