To anyone on their first season of commuting, this time of year (around the equinox) is when the sun appears low in the sky, on an East-West axis, during normal commute hours.
If you ride on an E-W road, into a low sun, be aware that cars behind you have very poor visibility and no amount of fluorescent green or bright lighting can compare with thermonuclear fusion.
Similarly, cars coming towards you into the sun can't see you, so be alert for right hand turns.
