	Dear colleagues,

	Yesterday morning was received in IMO NEWS an e-mail from Bev Ewen =
(COAA, Portugal) announcing high meteor activity during July 11th in =
SL=3D108.73=B0 (2000.00) in basis to doppler radio observations. Our =
team of the Spanish Photographic Meteor Network (SPMN-SOMYCE) detected =
the same day an interesting activity from Pegasids (July). The =
observational data was sent the past days to Rainer Arlt and to IMO =
list.=20

	We note that Pegasids activity was unusual during July 11th (0145-0300 =
UT, with an important component of bright meteors and a ZHR near 15 =
meteors per hour. This increase is in good agreement with the expected =
solar longitude maximum of this minor shower according IMO radiant list.

	The same night a member of our network Juli Castellano-Roig observed 6 =
faint meteors radiating from RA=3D309=B0 & Dec=3D+67=B0 in the interval =
01h10-02h05 UT (approx. mean geocentric velocity 35km/s). After this =
interval the activity from this radiant was low or non-existent. =
Considering the uncertainty in the radiant visual position, possibly =
these meteors were Omicron Draconids.=20

	No other important activity was observed from other radiants during =
this night.

	We hope receive any July 11th observation from american groups in the =
interval of high meteor activity reported at COAA,
