I was walking across a parking lot and taking in the view of the bright stars when i took notice of a very distinct horizontal grouping of 9 arrows crossing the sky from the northwest to the southeast. the width of the arrow grouping was the width of my fist with a fully-extended arm. each of the 9 arrows would slightly vary their speed whereby each would slightly go ahead of another (exchanging leads with respect to each other) while all remaining in their general grouping (please see my illustration - shows the extent of the arrow lead-changing with one another). each arrow would ever so slightly pulsate with no specific rhythm making each arrow become more/less faint to make out. they crossed the sky in a period of 15 seconds (far too fast for me to bother to get any smartphone pics without missing it all together). please see my illustration attached herein.
