J= 15.29, J-K= 0.88 (2MASS). Red dwarf star based on Gaia EDR3 (absolute G= 10.3 mag, BP-RP= 2.98). Significantly brighter g and z magnitudes were recorded by SDSS compared to Pan-STARRS1 and ZTF. Possibly a UV Ceti-type flare occured during the time of the SDSS exposure acquisitions. Epoch: March 24th, 2006. No obvious flares were recorded in Pan-STARRS1 and ZTF data. |

SDSS and Pan-STARRS color image extracts, and a comparison between SDSS, ZTF and Pan-STARRS1 magnitude values. The time order of the SDSS exposures are r, i, u, z and g. Both SDSS g and z magnitudes are superior to those of Pan-STARRS and ZTF (especially that of the g filter). However, the SDSS, Pan-STARRS and ZTF r and i values are all comporable. These observations may indicate a rapid brightening that had become obvious only after the acquisition of the SDSS r and i filters, and that had already significanly progressed by the time of the z and g filters. |
