There are a number of spikes in the ACE data, which likely do not reflect the actual low energy proton rates at Chandra: *** Special Note on EPAM Proton Data: *** The EPAM LEMS120 instrument which provides proton data in the energy ranges 47-68, 115-195, 310-580, and 1060-1900 keV is oriented on the ACE spacecraft at 120 degrees off the sun-Earth line, back towards the Earth. A consequence of this is that "upstream" magnetospheric particle bursts are often seen in these data. These bursts are most noticeable in the lower energy ranges, can occur several times a day, and can last for tens of minutes. The proton data in the 761-1220keV range is derived from a different instrument (CA60) oriented more towards the sun and is typically not affected by these upstream bursts.
