TL;DR: In this article, the authors reported the discovery of the supernova iPTF 13dqy = SN 2013fs a mere 3'h after the explosion of a red supergiant.

TL;DR: Observations of iPTF14hls are reported, an event that has spectra identical to a hydrogen-rich core-collapse supernova, but characteristics that differ extensively from those of known supernovae.

TL;DR: In this paper, the authors used the Palomar Transient Factory (PTF) and iPTF SN spectroscopy databases to detect flash-ionized (FI) signatures in their first spectra.

TL;DR: In this paper, the authors found 12 Type II supernovae (SNe) with flash-ionized (FI) signatures in their first spectra, which constituted 14% of all 84 SNe in their sample having a spectrum within 10 days from explosion, and 18% of SNe~II observed at ages <5$ days, thereby setting lower limits on the fraction of FI events.

TL;DR: In this article, a sample of 57 R-band Type II supernovae (SNe) light curves is presented, with greater than 5 detections during the first 10 days after discovery, and a well-constrained time of explosion to within 13 days.
