Don't miss
another meteor shower... receive meteor activity alerts via
email!
This was the first website to offer a live "meteor activity
indicator". Now another first! It can offer you "High" or "Very-High" meteor shower activity alerts,
(almost) direct via
email!
Two alert levels are available. Please subscribe to both for the
fullest alert coverage. The trigger levels are now
changing hourly, shadowing the diurnal cycle of ups and downs. With this
UNIQUE system, it's now possible to have a high
alert at 17h UTC if a meteor shower comes along at that time, which was highly
unlikely using fixed trigger levels.
This graphic
illustrates how the the trigger levels vary during the day.

From 02.07.2007, the alert emails are hosted by
Freelists.org.
From 10.06.2008 both high and
very-high alerts will be sent to the "alert-h" address. To only
receive very-high alerts subscribe ONLY to the vh-alert address.
Select the alert
lists you'd like to receive.
Enter your email address
below, choose the action required and click "Go!" It's
that easy!
You may also set yourself to "vacation" to temporarily stop
receiving mails, or unsubscribe.
As always, the
alert service remains completely free.

EMAIL FREQUENCY
When a subscribed-for activity level is triggered, you should receive one
alert email. Should that alert level still be active 12 hours later,
you will receive another, and again every 12 hours if it
continues.
If you are subscribed to both alert levels, you will get a new email
each time the alert level changes, although you won't receive two
emails from the same alert level within 12 hours (in theory!) If the PC
the system is operating on gets restarted, a fresh alert may be issued
regardless if an alert level is active since the system will have
forgotten it!
Should any alert emails be issued in error (due to signal interference or
other factors), I'll issue a "False Alert" message, as soon as
I can, to whichever levels were triggered.
The Blog via email has subscribed to it a few automatic alert systems,
such as the DX Robot
which monitors auroral and sporadic-E amateur radio contacts. By nature, these are intermittent, but are
occasionally very active. Also posted there are information and admin.
messages from me which are relevant to this website. Messages may contain
images or video attachments which may be several MB in size.
HOW TO UNSUBSCRIBE
Follow the instructions at the bottom of every alert email, or use the
options on this page.
NOTE
This system is under constant review. If you start
receiving excessive emails from the alert systems, or think that the system
has been compromised in some way or not working, please contact
me urgently to let me know.
