They are not well positioned to do that. You have to be in a very narrow path. But a properly positioned ground telescope could learn quite a lot about the star by studying the light curve. In some ways, events like this can give more detail than even the Webb can do. We can also learn about the asteroid by studying the light curves from several telescopes in different positions.
This is the type of event where high speed video gives better data than a long exposure. It will only be 12 seconds from beginning to end at any viewing site. And it will cross the earth in 18 minutes.
