AB In general, meteor and fireball imagingsystems operate during the night, as these mostlyemploy high-sensitivity recording devices that getfully saturated even under twilight conditions. Lowsensitivityvideo cameras can be an option to monitorfireball activity in broad daylight [1], although thecalibration of the images to get precise astrometries ismore complex. But some high-sensitivity CCD cameraswith attached autoiris lenses can also operate forsome period of time before sunset and after sunrise.These have the advantage that image calibration isstraightforward, as these cameras can reach a limitingmagnitude of +3/+4 and, so, stars recorded by thesame devices during the night can be used as a referencefor the astrometric calibration of fireballs recordedduring the day. This can be very useful to getprecise trajectory, radiant and orbital information ofvery bright bolides that occur in daylight conditions.Some of the meteor observing stations operated bythe SPanish Meteor Network (SPMN) are currentlymonitoring the night sky with high-sensitivity CCDvideo cameras configured in such a way that they canalso operate during a part of the day. In this context,we present here the preliminary analysis of a threestationsporadic diurnal fireball with an absolute magnitudeof about -8±1 imaged at dawn on June 1, 2011.
