Yes...those seem to be individual traders considering how the selling is going off and the lot sizes. The bid's disappearing frightens some, while other know not to place an order on the bids when the support is lacking as it will help them collect on the cheap. Either way, looking like there were 3 orders up for sale, now the 17's are up...IMO you get this kind of trading when folks get impatient and want to chase something they see running.
