They just HELD the launch! Cloud ‘Anvil rule’.

What does that mean?

Anvil clouds are thunderclouds

Thunderclouds are almost a daily occurrence in Florida but usually starting in late May.

Launch from FL, booster landing hopefully in the pacific off of CA.

The booster doesn't go that far. It will come down just a few miles off the Florida coast.

Rescheduled launch date is for tomorrow at 4:10pmEST. 50% chance of launch ‘go’ due to weather forecast.

Why don’t they launch around 11:00 AM? Much less chance of thunderclouds that time of day.

Anvil clouds are when the main shaft(s) of a thunderstorm reach up into upper high winds, often blowing hail out of the storm shaft to come down on unsuspecting people, cars, and the occasional spacecraft.

Anvil clouds are thunderclouds

Am aware of that, but still don't know what is the "anvil rule".

Is the rule that if they see one, they abort? Does it have to be within a certain distance, or a certain size? I'm just wondering what is the rule they have for dealing with anvil clouds?

Seems like a lot of money (launch scrub costs) to toss away for a not clearly obvious problem.

The reason they are skittish about thunderstorms:

Anvil cloud within 10 miles of launch ==> NO GO

Well I guess they have figured out the risks better than have I. I'm not going to second guess anybody's decision when it's their money on the line.

Its the inclination of the orbit of the ISS. The inclination is 51.65 degrees. This is typical of spacecraft accessible from Russia. You need to launch at a time when the ISS will fly/had flown over Florida. I'm not a rocket scientist, but I'm thinking there may only be one launch window per day. and they are just over 24 hours apart.

No. Taking supplies to the ISS.
