Comet C/2003 T4 (LINEAR) exhibit a large asymmetry in brightness before andafter perihelion, when it became much fainter. Large non-gravitational forcesshows that mass of nucleus doesn't exceed 2.51*10^11 kg, which is nearly doublethan previously disintegrated comets C/2012 S1 (ISON) and C/1999 S4 (LINEAR).Amount of water mass loss of C/2003 T4 in interval between 70 days before to 60after perihelion, was nearly 3.16(+/- 0.60)*10^10 kg or >13 % of total nucleusmass and >21 % for C/2012 S1, which is much larger than value >7 % previouslystated for C/1999 S4.
