In this note, we improve the lower bounds for the maximum size of thekth largest eigenvalue of the adjacency matrix of a graph for several values ofk. In particular, we show that closed blowups of the icosahedral graph improve the lower bound for the maximum size of the fourth largest eigenvalue of a graph, answering a question of Nikiforov.
