This source was reinstated on the Working List of Visual Meteor Showers after its unexpected return in 1998, when ZHRs of 50 鈥?00+ were visible for more than half a day. A further outburst of similar length, but with ZHRs of ~ 20 鈥?0 was observed on 2004 June 23, a date before definite activity had previously been recorded from this shower. We encourage all observers to routinely monitor the expected activity period, in case of future outbursts. Prior to 1998, only two definite returns had been detected, in 1916 and 1927, and with no significant reports between 1928 鈥?997, it seemed probable these meteoroids no longer encountered Earth. The dynamics of the stream were poorly understood, although recent theoretical modelling has improved our comprehension. The shower's parent Comet 7P/Pons-Winnecke has an orbit that now lies around 0.24 astronomical units outside the Earth's at its closest approach. It was last at perihelion in 2002, and is next due in late 2008. Consequently, the 1998 and 2004 returns resulted from material shed by the comet in the past, and which now lies on slightly different orbits to the comet itself. Dust trails laid down at various perihelion returns during the 19th century seem to have been responsible for the last two main outbursts. There were no predictions in force for possible activity in 2007 at the time of writing, but the approach of June's second full Moon on the 30th will create problems for observations of the 1998 repeat time anyway (given above). Moonset between 1h 鈥?h local time will allow a short 鈥?in some areas very short! 鈥?darker-sky interlude for those mid-northern places where all-night twilight does not occur in June, as from here, the radiant is at a useful elevation for most of the short summer nights. All observing techniques can be employed.Does anyone know if a meteor shower is going to happen in the constellation of Bootes in a few days or weeks?No, sorry.

There are no meteor showers in Bootes. This link gives all of 2007 meteor showers and a brief description of them.
