Next Friday (2/13) at 4:43pm local time (21:43 UT) there is a predicted -8 flare for my work location (39.1861N 76.6869W 34mASL). It will be nearly vertical (89 deg el). At 4:43pm yesterday I noted the brightness of the sky. Twlight isn't until about 6:10pm. A question for the people on the list who have seen daytime flares: How long are they visible? The evening and twilight flares that I've observed are typically visible at 1x for as long as 15 secs. I'm hoping for about 5 seconds for the daylight flare. Thanks.
