  The Solar energetic particle analysis platform for the inner heliosphere
(SERPENTINE) project presents it's new multi-spacecraft SEP event catalog for
events observed in solar cycle 25. Observations from five different viewpoints
are utilized, provided by Solar Orbiter, Parker Solar Probe, STEREO A,
BepiColombo, and the near-Earth spacecraft Wind and SOHO. The catalog contains
key SEP parameters for 25-40 MeV protons, 1 MeV electrons, and 100 keV
electrons. Furthermore, basic parameters of the associated flare and type-II
radio burst are listed, as well as the coordinates of the observer and solar
source locations. SEP onset times are determined using the Poisson-CUSUM
method. SEP peak times and intensities refer to the global intensity maximum.
If different viewing directions are available, we use the one with the earliest
onset for the onset determination and the one with the highest peak intensity
for the peak identification. Associated flares are identified using
observations from near Earth and Solar Orbiter. Associated type II radio bursts
are determined from ground-based observations in the metric frequency range and
from spacecraft observations in the decametric range. The current version of
the catalog contains 45 multi-spacecraft events observed in the period from Nov
2020 until May 2023, of which 13 were widespread events and four were
classified as narrow-spread events. Using X-ray observations by GOES/XRS and
Solar Orbiter/STIX, we were able to identify the associated flare in all but
four events. Using ground-based and space-borne radio observations, we found an
associated type-II radio burst for 40 events. In total, the catalog contains
142 single event observations, of which 20 (45) have been observed at radial
distances below 0.6 AU (0.8 AU).
