Hi all,
1. NOVA in CYGNUS: A fairly bright Nova has been discovered in Cygnus by
Akihiko Tago in Japan on the evening of March 15 at magnitude 7.4.
Another estimate next evening indicated a magnitude of 6.7. It may still
be brightening or may have already reached maximum, so observe it if you
can. At around 7th magnitude, it's within easy reach of binoculars, but
it lies in the Milky Way so it's in a crowded starfield, and may not
be that easy to identify at first.    A nova is a star, usually a member
of a close binary system where one star is accreting material from
another, and undergoes a a colossal explosion, blowing off the outer
layers of the star, increasing its brightness by may thousands of times.
   This nova is circumpolar in Ireland, but it it's quite low when at
lower culmination (due North). It's best seen later in the night: by
midnight it will be 10-14 degrees up (depending on your latitude) in the
NNE. Its position is: R.A: 20h 28m 12.5s Dec: +41 deg, 48' 36.5" (2000.0
co-ordinates) I'll send a map out separately shortly for those of you
without deep star atlases or a PC sky programme.

3. IAA Public Observing Evening, WWT, CASTLE ESPIE: The Irish

5. BAA Tribute to Sir Patrick Moore: On April 24, the BBC's Sky At Night
programme and Sir Patrick Moore (a BAA member for more than 70 years)
celebrate 50 years of continual broadcasting: the world's longest
running television programme with the same presenter.    Many
astronomers, amateur and professional alike, have been inspired by
Patrick and the programme over the years.  Following a suggestion by one
of the BAA's younger members, Philip Jennings, they are giving members
and others an opportunity to send a personal greeting to Patrick on this
unique achievement.  Visit this webpage where you can add your name and
also send a personal greeting or message.  The address is:
   They plan to present Patrick
with his "Sky at Night at 50" greetings card and read out some of your
messages on the anniversary date.  Hopefully this will come as a
pleasant surprise for him.  (via Richard Miles, BAA President)

Clear skies,
Terry Moseley
