- Chiron has variable activity and V mags are important.
- 1994 AW1 has an unusual light curve - worth observing in
- Phaethon makes a close approach in 1997.
- 3691 1982 FT is a slow rotator with a period of around
- 253 Mathilde is a NEAR target
- H10 values are of interest to professionals. Magnitude
estimates, particularly of fainter comets are therefore
- Comet hunting, particularly in twighlight conditions is
still worthwhile, but professional searches will soon be
scanning all the dark sky areas to 19th mag.
- 46P/Wirtanen (1997, 2008) and 81P/Wild 2 (1997) are
spacecraft targets so observations are important. Other
targets are 22P/Kopff, 29P/SW1, 76P/WKI, 90P/Chiron.
- Its worth monitoring asteroids in cometary type orbits
(eg Phaethon, Oljato, 6144 1994 EQ3, Hidalgo, Hephaistos) in
case they outburst. Similarly it is worth monitoring distant
- Nuclear magnitudes following an outburst can be useful,
but should always use the same telescope and magnification.
- Disconnection events (and kinks, rays, knots etc) in
plasma tails are only likely for comets in equatorial
- Its worth watching minor showers, particularly those
associated with long period comets - you might see an
outburst. Its possible that one or two occur each year.
- The Leonids are expected to show enhanced activity from
1998 to 2003, storms in 1999 and 2000 and minor enhancment
from 2003 to 2006. There were two peaks in 1965 at solar
longitude 234.12 and 235.16.
- There were an unusually large number of Taurid fireballs
in the last 10 days of October 1995.
- It is possible to see shower members outside the
normally accepted limits, eg NDA Aug 1 - Sep 3, PER Jul 12 -
Sep 8, LEO Nov 8 - Dec 3, GEM Dec 3 - 15.
- The Perseids may have multiple peaks.
- The alpha circinids may outburst in 2003/04
- There may be a further alpha Monocerotid outburst on
1996 November 21 07:30
- 1995 O1 is unlikely to produce meteors, but its worth
