Abstract
A recent RNAAS, analyzing data from the WASP survey, claimed that the star TYC 2623-1439-1 underwent a 1% dimming that lasted for 11 days, and interpreted this as a transit of a wide-orbiting planet. However, WASP survey data is prone to red noise. I show that the same dip is seen on a nearby star, and conclude that it is a pipeline artifact rather than being real.This publication has 7 references indexed in Scilit:
