We report results from the first half of the 2018 Mexican Photometry Campaign. This period consisted of a total of 42 observing nights distributed on three observatories. From these data we have obtained lightcurves and synodic rotational periods for 6 asteroids. 1491 Balduinus resulted in a period of P = 15.3044 ± 0.0057 hr; 1856 Ružena, P = 5.957 ± 0.001 hr; 3394 Banno P = 7.344 ± 0.0002 hr; 3877 Braes P = 5.8155 ± 0.0005 hr; 7430 Kogure, P = 17.998 ± 0.076 hr; and for 2001 KB67, P = 6.357 ± 0.0012 hr.
