OVSA-LWA Spectroscopy AI Summary for 2026/04/13

Section: Summary
The solar radio activity on April 13, 2026, was very quiet, with no significant radio burst events detected. Solar tracking by the OVRO-LWA array began at approximately 13:20 UTC, after which the spectrograms showed a stable background flux level of approximately 1 sfu. No radio bursts exceeding the 10 sfu threshold were observed throughout the day.

A few marginal, low-intensity features consistent with weak Type III bursts were visible, including a faint drifting feature at 16:19 UTC, a brief vertical burst at 19:18 UTC, and a minor group of weak bursts between 22:34 and 22:36 UTC. These events remained close to the background level with estimated peak fluxes well below 10 sfu and do not constitute significant solar activity.
