I'm interested in this spiral galaxy. Is it forming stars?

Welcome to Galaxy Zoo, pinkfiddler!
Here's how SDSS J151705.37+150642.8 - the galaxy in the center - looks, in DR12 SDSS:
The pale-blue and white in the DECaLS image, and the blue and purple in the SDSS one, point to a lot of on-going star formation.
And the SDSS spectrum clinches it (look at those emission lines!):
Hope this helps, and happy hunting! 😃
