We present a catalog of compact sources detected in the MIPSGAL 24 microns survey data. These small (< 1 arcminute) rings, bubbles, disks or shells are pervasive through the entire Galactic plane in the mid-infrared. Over 400 such sources have been identified from visual inspection of the MIPSGAL mosaic images. Their distribution is approximately uniform in Galactic latitude and longitude, and the average density is found to be around 1.5 "bubble” per square degree.
We have identified 10% of these objects by extensive browsing of available catalogs from the VizieR data base. The majority of the already known "bubbles” were found in the MASH Catalogue of Planetary Nebulae (Parker et al. 2006) and in the Catalogue of Galactic Planetary Nebulae (Kohoutek 2001). Three supernova remnants (SNR) and one post-AGB star were also identified from published catalogues. The remaining 90% of the bubbles are yet unknown objects.
