New L-1 weather forecast. 25%->50% 'Go' for June 15. 40%->70% 'Go' for June 16. All Additional Risk Criteria are Low.
Note: This does not mean that SpaceX is necessarily going to make a launch attempt on June 15.

Some places are now listing NET June 23 launch date, but I'm guessing that's based on the assumption that Astra 1P will now take precedence. Is that confirmed?
From what I can tell, the weather report for 10-2 lists today and NOTAMs haven't been cancelled yet, so I think SpaceX might still be hoping to launch today. Any idea if the rocket is still vertical? That would be a good indication.

https://twitter.com/spaceoffshore/status/1801969013045498278 Checking in with the SpaceX recovery fleet for clues, it looks like the Starlink 10-2 mission is standing down and the next mission from SLC-40 will be SES-24.
JRTI droneship appears to be heading to the expected LZ for SES and Doug looks to be returning to Port Canaveral.

Tough week dealing with production challenges and then a rare scrub at engine startup yesterday on 10-2. Unfortunately there is a real issue so we need to go inspect the hardware in detail on this vehicle. Rocket will get set to the side and we’ll pivot to SES as the rocket and payload are ready to rock. Painful, but safety and reliability are the priority.
This will be the first week we’ve gone without a Falcon Launch in a long time. Unplanned downtime due to weather or unexpected issues happens, it’s how we respond that matters. The Launch business takes grit and when things go wrong, our true form comes to life.
Bring it on!!!

When was the last launch abort post-engine ignition? I feel like I remember one early this year or last year.

According to
SFN it was GPS III SV04 on October 3rd 2020. But after watching the video, I'm not sure the engines start up.
Starlink 6 on March 15th 2020 definitely aborts at T-0.

I just did a lot of searching, although there have been previous pre-T0 pad scrubs (> 00:01), this is (IMO) the first time an F9 has aborted post-ignition. If someone comes up with a better answer, I'll stand corrected.
Update: Apparently I corrected myself and found the first occurrence. See my next post.

Nope, that aborted at T-3 sec. (
SOURCE) but eventually, launch later that same day after recycling and moving some marine traffic away from the flight path.
https://forum.nasaspaceflight.com/index.php?topic=21869.msg600684#msg600684This may be the first post-ignition abort.
Saturday’s launch was aborted when the flight computer detected slightly high pressure in the engine 5 combustion chamber. During rigorous inspections of the engine, SpaceX engineers discovered a faulty check valve on the Merlin engine. The failed valve was replaced on Saturday and after thorough analysis the vehicle has been cleared for launch.

what about this
this very much looks like a post ignition abort based on the steam from the flame diverter!

For those of you struggling with the embedded links as I was on another device:
rockenthusiast pointed to the Mar 15, 2020 post ignition abort of the sixth Starlink flight.
I have that as the 88th flight of F9, and 365 or so Falcon launches ago.
catdlr pointed to the May 19, 2012 post ignition abort of CRS-2 which I have as the fifth f9 flight.
That was way back in the version 1 of everything, or version 0.
As it was just pointed out by someone on NSF, never say never, but post ignition aborts very rare.
