<p class="ql-align-justify">The F2 region critical frequency (<em>f</em><sub><em>o</em></sub><em>F2</em>) and peak electron density (<em>N</em><sub><em>m</em></sub><em>F2</em>) morphology was investigated over Ilorin (latitude 8.31°N, longitude 4.34°E) during a Low Solar Epochs (LSE), a station along the equator anomaly trough. Diurnally, <em>f</em><sub><em>o</em></sub><em>F2</em> and <em>N</em><sub><em>m</em></sub><em>F2</em> are visibly more prominent during the day than at night with two characteristic peaks: pre-noon and post-noon peaks. The <em>f</em><sub><em>o</em></sub><em>F2</em> and <em>N</em><sub><em>m</em></sub><em>F2 </em>pre-noon peak magnitude range: (7.7–8.3 MHz) and (7.3–8.6) × 10<sup>11</sup> /m<sup>-3</sup>respectively is less compared to the <em>f</em><sub><em>o</em></sub><em>F2</em> and <em>N</em><sub><em>m</em></sub><em>F2</em> post-noon peak magnitude range: (7.3–9.7 MHz) and (6.7–11.7) ×10<sup>11</sup> /m<sup>-3</sup> respectively. Seasonally, the highest values were attained during the post-noon peak in the equinoctial months compared to the solstices months, and also, annually, the post-noon peak is higher than the pre-noon peak. The rapid electron drift away from the equator is responsible for the sharp drop in <em>f</em><sub><em>o</em></sub><em>F2</em> and <em>N</em><sub><em>m</em></sub><em>F2</em> after sunset in all seasons. Seasonal peaks in <em>f</em><sub><em>o</em></sub><em>F2</em> and <em>N</em><sub><em>m</em></sub><em>F2</em> are suspected to be controlled by the enhanced E × B drifts and the onset and turn-off of solar ionization, which is consistent with some earlier results obtained at some stations in the African region during low solar epoch periods.</p><p class="ql-align-justify"><br></p><p><br></p>
