Second asteroid in this photo.
I now check when I find an asteroid, to see if there are others heading in the same direction - and sure enough - there is - though only showing up in two frames (and partially in a third). Not quite sure of all the talk options - all I want to do is make the science team aware of my observations - and not necessarily start a long discussion. Am I doing this best by creating a discussion - or using a hashtag (and are there any standard hashtags - where do I find them. All questions from a 68yo who is not too familiar with social media.
