Left: Comparison of the [ESP] zeroth-order signal ("QD"), in red, and the GOES low-energy channel (blue). Two features are striking: first, the EVE signal peaks later, and second, it has a substantial preflare excess. These both point to longer effective wavelengths. Right: A blow-up of the preflare variation, showing how much better the ESP photometry (1/4 sec binning, much lower noise) than GOES is (3 sec binning, much greater noise).
