                         near-equatorial ionosphere (Arecibo: 28.17°N, L = 1.3) is 
                         investigated for the first time. Although the HSS did not lead to 
                         any significant geomagnetic storm activity, the ionosphere over 
                         Arecibo became hotter and expanded significantly in altitude as 
                         compared to a non-HSS interval. The O+/H+ transition height hT 
                         increased by ~200 km in the daytime and by ~100 km at night. At 
                         the hT, the peak ionospheric electron and ion temperatures 
                         increased by ~200500 K during day and by ~5070 K at night. While 
                         the O+ ion concentration exhibited an overall enhancement, deep 
                         penetration of the H+ ions below hT are observed during the day. 
                         The noontime peak electron density was ~4 times higher during the 
                         HSS event compared to the non-HSS interval. We present three 
                         possible mechanisms to explain this topside ionospheric heating.",
