A. de Ugarte Postigo (HETH/IAA-CSIC, DARK/NBI), D. A. Kann, C. Thoene,

report:

We observed the field of GRB 200303A (Cenko et al. GCN 27297) with CAFOS, 
on the 2.2 m telescope, at Calar Alto observatory (Almeria, Spain). Observations 
consisted of 5x360s in R-band with mean epoch 03:48:02 UT (1.249 hr after the 
burst).

Our initial analysis does not reveal any object within the refined error box (Goad 
et al. GCN 27300) down to a 3-sigma limit of R(AB) > 24.0 mag, with photometry 
performed against SDSS field stars.
