[Adam]

Hello,

I wanted to know how the frequecy uptdate for the kp indice because it's say it's for the 15-18 utc but in my country it's 21:13 utc so i wanted to know when the kp indice is uptade thank you

The three-hourly Kp is updated some time after the three hour period has passed. So the 18 to 21 UTC update should indeed come somewhere after 21 UTC. However, I don´t know exactly how long after the three-hour period has passed, the update becomes available and how long time it takes for it to be updated on the website but Sander might know more on this.

Each three hours the Kp index get's updated when all magnetometer stations have finalized their readings from that period. Normally this happens 5 to 10 minutes past the period.

It also depends on when we refresh the data on the website but it shouldn't be too long after the 3-hour period has passed.
