Not necessarily... because the rest of the network would have rejected the transaction as "dust"... most of the nodes would have refused to propagate the transaction... and you transaction would have effectively "disappeared"... which it appears to have done.

At this point in time, your only hope is that CoinJar refund you your 989 sats and your CoinJar points.

In the future, I'd recommend you don't try and send anything less than 0.001 BTC from CoinJar at the very minimum. Given that CoinJar are using a default of "0.0005 bitcoin transaction fee"
