Astrophysical transient events like Gamma Ray Bursts (GRBs) have always been promising
candidates for multi-messenger astronomy, with electromagnetic and gravitational wave signals
having already been observed in GRBs such as GRB 170817A. The neutrino signatures of these
bursts have been long-awaited as well, with many models predicting different spectra. Most of
these searches have been in the hundreds of GeV to PeV range. However, as different models
indicate a possible lower energy neutrino signal, we intend to expand this search to the lowest
limits of IceCube (0.5-5 GeV) as well. With the plan to look at more transient events, we present
the result of the first IceCube search for < 5 GeV astrophysical neutrinos emitted from a GRB,
for GRB 221009A; the brightest GRB ever observed. Furthermore, we present plans to improve
the observations of < 5 GeV neutrinos in IceCube, with which we plan to probe more transient
events in the future. These improvements include the addition of direction reconstruction at these
energies, and optimization of the noise rejection. With these improvements, GRB 221009A is just
the start of the low-energy neutrino search from transient events with IceCube.
