What do you want to do with it ?
You can turn it into uncompressed public key:

publicKey = '04' + X + Y
publicKey = 04f9308a019258c31049344f85f89d5229b531c845836f99b08601f113bce036f9388f7b0f632de 8140fe337e62a37f3566500a99934c2231b6cb9fd7584b8e672

Or turn it into a even compressed public key:
publicKey = '02' + X
publicKey = 02f9308a019258c31049344f85f89d5229b531c845836f99b08601f113bce036f9

Or turn it into a odd compressed public key:
publicKey = '03' + X
publicKey = 03f9308a019258c31049344f85f89d5229b531c845836f99b08601f113bce036f9

One of the last two is invalid.
You have to turn the X part of the public key into binary BASE2 form and look if it's odd or even:
0xf9308a019258c31049344f85f89d5229b531c845836f99b08601f113bce036f9 ==
0b11111001001100001000101000000001100100100101100011000011000100000100100100110 1000100111110000101111110001001110101010010001010011011010100110001110010000100 0101100000110110111110011001101100001000011000000001111100010001001110111100111 000000011011011111001
Look at the last bit it's a 1 so the compressed public key is odd so it starts with '03'

You can also convert it to WIF:

5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreB1FQ8BZ uncompressed

KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rFU74sHUHy8S compressed

And you can calculate various addresses but that is far past private to pubkey
