We present the specific star formation rates for MIPS 24 micron selected Coma cluster galaxies. We build galaxy spectral energy distributions using archival optical and Mid-IR photometric data from Sloan and the Spitzer Space Telescope, as well as new near-IR data we have collected at Palomar. Spectra of 100 Mid-IR selected members are collected and best fit model spectral energy distributions are found for each member galaxy to determine total infrared luminosities and galaxy masses. With the help of archival FIRST radio data, we quantify the amount of AGN contamination, and compare obscured starformation rates to unobscured rates derived from extinction-corrected Halpha line measurements. Finally, we examine the location of the strong starbursts in the cluster to better understand the galaxy activity in Coma.
