I would estimate it is something that I have experienced only during the past two to three weeks. However, it is frustrating as I prefer to release the shutter 3-4 seconds prior to the proposed start of flaring so as to minimize the affects of skyglow and, yet, with these early arrivals I must now release the shutter 10-15 seconds earlier. I am relieved to see that I am not the only experiencing this premature flaring. I would also love to hear of any explanations. It is also not an issue of H-A vs Iridflar as the premature flaring is relative to both sets of times.
