The decline/fading mentioned by Clay is not an actual fading of the DN but represents the fading part after the s/hump.
If observations were done an hour earlier they would have shown a 'brightening'...
My own observations last night showed that ASAS 102522-1542 is still humping and at the same average brightness as it was a couple of nights ago. Too strong wind and threatening weather limited the observations to only one cycle and a bit.
