I used both my 10x50 binoculars and just my eyes. I did see 3 approx. +2 flashes and one +3 flash with my eyes. I only saw every third flash, even with the binoculars. I measured two of these periods at 527+-1 sec, which gives a close-to-the-above average 87.8 sec / flash. It was rather fun trying to estimate where in Orion I would see the next flash...with over 4 minutes 'tween the primary flashes I had plenty of time to make an estimation. On a different note, these days Mercury+Jupiter+Venus+Saturn make a nice bright string of planets soon after sunset.
