EC 53 is located in Serpens Main at R.A. = 18:29:51.2, Dec. = 01:16:39.5. This image is a co-add of all 850 micron Serpens Main observations obtained by the Transient Survey. These observations were taken using the Submillimetre Common User Bolometer Array 2 (SCUBA-2) at the James Clerk Maxwell Telescope (JCMT).
The 850 micron light curve of EC 53 obtained by the Submillimetre COmmon User Bolometer Array 2 (SCUBA-2) at the JCMT. The dashed lines show the x-axis boundaries for the infrared data presented below.
