This catalog lists the proton enhancements from the Wind/EPACT instrument since 1996 in the two energy channels available. The catalog is organized as a table that presents the solar energetic particles (protons) observed during solar cycle 23 (1996-2008) and the ongoing solar cycle 24 (since 2009). The catalog provides the following information: onset, peak times (in UT) and peak proton intensity at 19÷28 energy channel and also the peak proton intensity at 28÷72 MeV energy channel. In addition, the solar sources (flares and coronal mass ejections, CMEs) of the proton events are identified, where possible, with their properties noted. Further information is given as a comment.
Extensions of the catalog (or corrections if needed) will appear regularly online.
For preliminary description and results of the catalog, see
Miteva et al. (2016)
and Miteva et al. (2017)
Explanatory notes:
Proton data: from CDAweb database provided with 92-sec time resolution.
Onset time: identified as the time of 3-sigma intensity value above pre-event level.
Peak time: identified at the maximum of the particle profile (local enhancements are not considered).
Jp: peak proton intensity after subtraction of the pre-event level.
Fp: onset-to-peak proton fluence.
The reported here onset/peak times and Jp are based on 5-point smoothed data.
Abbreviations:
N/A: onset not found and/or it was fully masked by previous ongoing event
nd: next day
pd: previous day
p: peak is poorly defined
SXR: soft X-ray
u: uncertain
v: visual
