Subscriptions to the AAVSO High Energy Network are now done via the Blue & Gold section of our website. Please log in to Blue & Gold to subscribe or modify your existing subscriptions.

If you have not registered as an AAVSO observer, you may do so here. Registration is free; membership in the AAVSO is encouraged but not required. If you are an AAVSO member or observer but don't have a Blue & Gold account, you can register here.

Note: if you are subscribed to AAVSO GRB alerts, have an existing Blue & Gold account, but do not see your subscriptions linked to that page, it means we could not find your existing subscription address in our membership record. Please contact aavso at aavso dot org and tell us the email address at which you receive GRB Alerts and your Blue & Gold username (username only, not your password!). We will link your subscription to your Blue & Gold account in 1-2 business days.
