More than once we (Chris and I) experience that a mail send to the
SeeSat_L community is not delivered. Our bypass is that it is sent to my
work emailaddress from which I (Bram) send it like in this case.=20

>> On May 12, 21h42 UT, we (Bram + Chris) observed a
>> magnificent zenith pass of Iridium 11. I made 2
>> photographs of it. Flashes of all magnitudes down to
>> about -3 observed at 1x. All flashes were too short to
>> measure visually, which make them difficult to determine
>> their brightness. I saw it blinking from just below Polaris
>> to 80=B0S. Then it became invisible, but at about 40=B0S we
>> saw another 3-4 flashes. The pattern seemed irregular,
>> but I measured several periods of 5.5". I saw also
>> flashes in between.
>>
>> A few minutes later (21u48) We saw at 20=B0NW (above
>> Capella) another bright flasher moving S-N. I don't
>> remember the flashing pattern but I also photographed
>> this one. A few seconds before exposure I saw a -5 flash
>> from this sat! However, the flashes were very short also
>> in this case. Which satellite was this?
