Why are your alerts always 24 to late?
Do you mean you received the email late? I subscribe to myself and it is almost instant. I wrote this post when I knew the good auroras were imminent. This (the great solar winds and trending southward Bz) cannot be predicted more than a day in advance unless it is a CME with arrival times.
DOES YOUR SITE NOTIFY OF AURORA THAT MIGHT BE REACHING INTO THE UNITED STATES AND IF SO DO YOU NOTIFY AS TO HOW FAR SOUTH INTO THE UNITED STATES??? THANK YOU …
Yes, if it is apparent that it will happen. You’ll want to watch for Kp 5 or higher. You didn’t state your exact location. You can get free email alerts from NOAA Space Weather for geomagnetic storm watches and warnings. This is when they think a Kp 5 or higher will happen. Although a Kp level is no guarantee of auroras, it is an indicator that there is a possibility. The watches and warnings can be several hours in advance. I will typically make a similar post about it, but NSW will give you the exact data as it happens, whereas I may be asleep or at work. https://www.swpc.noaa.gov/content/subscription-services
