A survey for variable stars with small telescopes: IX -- Evolution of Spot Properties on YSOs in IC5070

We present spot properties on 32 periodic young stellar objects in IC 5070. Long term, \(\sim\)5 yr, light curves in the \(V\), \(R\), and \(I\)-bands are obtained through the HOYS (Hunting Outbursting Young Stars) citizen science project. These are dissected into six months long slices, with 3 months oversampling, to measure 234 sets of amplitudes in all filters. We fit 180 of these with reliable spot solutions. Two thirds of spot solutions are cold spots, the lowest is 2150 K below the stellar temperature. One third are warm spots that are above the stellar temperature by less than \(\sim\)2000 K. Cold and warm spots have maximum surface coverage values of 40 percent, although only 16 percent of warm spots are above 20 percent surface coverage as opposed to 60 percent of the cold spots. Warm spots are most likely caused by a combination of plages and low density accretion columns, most common on objects without inner disc excess emission in \(K-W2\). Five small hot spot solutions have \(
