Descripción
We report YALO consortium observation of a mini-outburst of Aquila X-1 = V1333 Aql, which occurred between July 04.27 and 07.29 UT. This X-ray binary outbursts approximately once per year, and most recently entered a mini-outburst during May 2000 (IAUC 7423,7429). We have been monitoring this source since April 5 in R using the YALO 1-m telescope at CTIO. Compared to the quiescent average magnitude, which fluctuates by less than 0.1 mag, the source had brightened in R by 0.20 +/- 0.02 mag on July 04.27 UT and peaked at 0.31 +/- 0.02 mags on July 05.26 UT.
