Candidate high-ionization Starburst / Green Pea galaxy at RA 154.2762

Interesting things

Hello team,

Reporting a potential high-ionization starburst (Green Pea / Blueberry class) galaxy candidate discovered during a manual coordinate sweep.

Visual Profile: Object exhibits a highly concentrated blue-white stellar core completely enveloped by an intense, saturated neon-green/turquoise emission halo. This signature strongly points to massive [OIII] oxygen line emissions from rapid star formation. There are no local bright foreground stars or diffraction spikes in the radius to indicate an internal lens reflection or optical camera artifact.

A coordinates cross-check returns no matching documents in standard literature. Requesting a look from the science team or target catalog review.

Best regards.

This is a star - it has a measured proper motion with Gaia -

The colors you mention are because the star saturated the CCD detectors, and then the software that assigns colors gets a bit confused.

cheers,

Got it. Thank you for cross-matching the coordinates with Gaia data and explaining the CCD saturation effect, Dustin! Excellent learning checkpoint for artifact filtering. Moving on to scan the clean deep fields.
